Domesticating wild rats caught at adulthood

I'm a rat owner...sort of. I caught an Eastern woodrat in (appropriately) my woodshop. Evidence of her residency became apparent before I even knew she was there. Cords and wires were severed, and almost every one of them looked like it was cut with a sharp blade, not chewed. A couple of the severed plugs were nowhere to be found. I started losing halfway-finished projects. Pen turning is the latest facet of woodworking I'm trying to perfect, and the hardest part is trying to get the perfect shine. Sometimes, I'll work on polishing several pen barrels at a time before I assemble them, but production was halted when I started losing pen barrels. And drill bits. And one half of a yo-yo I was making from purpleheart. Then my broom started balding; half its bristles were gone. The only two people that set foot in my shop regularly are 14-year-old son, and my neighbor, Jamie. I was getting plenty heated, trying to figure out which one of them thought he was doing something hilarious.


I guess I should be flattered that my efforts have been met with approval from the most discerning aficionados of shiny loot.

Then I found the first pack rat stash while I was straightening up the shop. Everything was just piled in one corner, even the broom bristles and electrical cords. I also found several blue shop towels, a lot of used segments of sandpaper rolls I had used on the lathe and tossed to the floor, packing peanuts, a pack of Jamie's cigarettes that was still halfway full, my new torch lighter that was only three days old when I lost it, several crushed aluminum cans (I recycle), some unused wood pen blanks I had actually ordered online and paid quite a bit for (Gaboon ebony is a frightfully expensive wood!) and one of my Kobalt screwdrivers. Even after finding the mess, I still had no idea how in the world everything had wound up in the corner. A few nights later, my shop guest made her first appearance. I work nights because Louisiana heat is murder when it's married to Louisiana humidity, and I was sitting at the workbench when she appeared two feet away from where I was sitting, smelled me, and scampered off. I had no idea what she was. I had never seen a rat before. I don't recall seeing one even in a pet store. She didn't look like any of the rats I had seen in movies or on TV, so I resumed my work, and thought about rodents.

A couple of nights after she made her debut, I saw her again around midnight, and texted Jamie. He had just gone to bed but decided that mystery rodents were more interesting...and he never has anything important to do, anyway. He brought a squirrel trap with him that looks like it was made before the wheel was invented. He ignored my suggestions to oil it, baited it with peanut butter, and set it a couple of feet from where I found the stash. Less than five minutes later, the rat came out, crawled into the trap without hesitation, and gleefully started grazing on peanut butter, perched right on top of the trip mechanism. I tapped Jamie, who stood up saw what was happening. It took about four seconds for him to realize what was happening, but once the light clicked on, he got mad and hollered something about "Yer not gettin' a free meal ya *******!" as he flailed his arms. The rat was out of sight before he got the third word out. Eventually, I came up with the idea to tie fishing line to the hook that restrains the spring-loaded door, and the next time she took the bait, I gave the line a sharp tug, and she was trapped.

I took this picture a few minutes later.


Poor thing was scared, and I was mystified. She looks like an overgrown mouse, not the beady-eyed things that come to mind whenever I think of rats. I worried that the trap's wires might hurt her feet, so I made a crappy box from 1/2" sheathing and hot glue, with a Plexiglass front and a lid that was too small to sit squarely on top. I skewed it a bit so it wouldn't fall in, and somehow managed to get the rat into the box.

Not long after dawn, Jamie came back into the shop with two baby rats he found outside. Instead of leaving them alone, he thought it would be a brilliant idea to pick them up and bring them inside. Damage was done, so I added two baby rats to the box. They were only about a week old, and they obviously belonged to the rat I had captured. Mama rat didn't abandon her concern about her predicament and immediately focus all of her attention on them, but I could easily see the familiarity she had with the babies.

About half an hour later, I looked up from the lathe just in time to see mama rat push the roof aside with her nose. She had actually climbed right up the sheathing and moved the roof enough to escape, and she didn't waste any time. "Screw you two kids, I'm outta here!" Gone.

At that point, the adventure changed from entertainment to responsibility. I hadn't researched anything about rats, and I just assumed that human scent would make her abandon her babies. So I immediately began learning how to take care of newborn rats, and even though they must be tended every 2-4 hours at that age, around the clock, I did a **** fine job. I actually got attached to them. They squeaked, they squirmed, they REALLY enjoyed the feedings, but they didn't make it. Poor things thrived for five days...their eyes were almost ready to open...but something (probably my fault) gave them a respiratory infection, I didn't have a way to help them, and the vet couldn't do anything (because it's illegal to treat wild animals) and I just watched helplessly as they gasped for air they couldn't get. I couldn't even give them a quick death because I was fervently hoping and wishing they would recover. But they suffocated in the open air before dying in my hands. I was both frustrated and depressed.



When I started noticing things were missing again, I looked in that corner and saw that mama rat had started a new stash. I set the trap, baited it with peanut butter, and caught her again, but she escaped as I was trying to transfer her to a different box. I caught her a third time. Got her in the original sheathing/hot glue box, but the too-small roof fell in, and the surprised rat took the opportunity to escape before the surprised woodworker could make any attempts to prevent it. I caught her a fourth time, she escaped a fourth time. When I caught her for the fifth time with the same bait, (peanut butter = crack for rats), I made a pretty decent rat habitat with solid wood and Plexiglass. I made an "external" room that had a screen floor (fireplace screen, not screen-door screen) for those private moments in every rodent's life (it was the bathroom, haha). The "bathroom" had a hinged ceiling so I could reach into the lower level of the cage to put food and bedding inside, and I put a heavy box of drill bits on top of that ceiling so mama rat wouldn't nose her way out again. The whole setup looked good for a hot glue job, but I was worried that there wasn't enough air flow because I used Plexiglass instead of wire (which I didn't have).

I didn't plan to keep her long, anyway, because it's almost impossible to tame a wild rat if it's caught in its adulthood, but oddly, she was showing a few domestic traits. She would approach the Plexiglass if I put my finger against it, she didn't shy away from my voice like she did throughout the first couple of captures, she was nibbling on the morsels I had put in with her, and then she was drinking water from a dropper I was holding for her through one of the many vents. I went to a hardware store to buy some hardware cloth to improve her air circulation, and stopped by the pet store for some rat treats. I brought the goodies into the shed, and...no rat. The entire bathroom had fallen off. Even if she wasn't in it when it fell, the sound of that box of drill bits hitting the floor probably scared her out of her mind.

I set the trap again, but I put it outside, in a covered area attached to the back of the shed. I caught her for the 6th time less than three minutes after I put the trap down, baited with more peanut butter. I was starting to think she was enjoying the dance. This time, I modified the box with the ill-fitting roof and made a decent habitat out of it. While she was chilling in that home (it was only about 12" x 12" x 12", I started working on a "tower" whose frame was an old waterbed headboard someone threw away. I spent many hours working on it, but she got away in transit from box to tower. For a few days after that, she wouldn't go near anything that smelled like peanut butter. But on day 5, I caught her again after baiting a trap with chocolate pie crust, and she got away again while I was transferring her, surprising me with her leaping prowess and climbing ability (she skittered straight up a wide sheathing board and was out of sight before I could even say, "You suck!"). Three more days passed before I caught her again...with peanut butter...and I successfully installed her in the tower. She completely bypassed all of the little steps and ladders I had put in, navigating by hardware cloth. While she was in the tower, I successfully fed her several kernels of sweet corn by hand, through the wires of the hardware cloth. I went inside the house, and when I came back out to the shop four hours later, she was gone again, having chewed through the sheathing I had used when I ran out of hardware cloth. I slathered an aluminum can with peanut butter and set the trap again, and caught her within the hour. She wasn't even panicking over being caught anymore. She's escaped nine times, but I've caught her ten times. I didn't even use a trap for #10: she hid inside a roll of roofing felt, so I put an aluminum can in each end to cut off another bid for freedom, picked the whole roll up, and held it vertically over the opening in the third cage I made for her until she crawled down into it.

That was two or three weeks ago. She can't get out of my latest cage, even after I added another level on top of it. So now, I have a trapped wild rodent. Killing her isn't an option for me. Dumping her in the woods far away from my house is almost a guaranteed death sentence. But I can't let her continue her mischief in my shop, so now I'm taking care of a wild animal. I had trouble giving her water, because she couldn't see either the dropper or the pipette I used, but I found that adding some fruit juice helped her find the tip by smell. I tried putting water in a clean juice cap, but she immediately spilled everything when she picked it up to "pack" it somewhere. After that, she just crapped in the water-filled lid and kept doing it every time I cleaned and refilled it. I spent two days teaching her how to use the water bottle, but she's a pro now, so I don't have to worry about dropper quenching.

I've made several modifications to the cages. I put an 11" mesh exercise wheel on the upper level, but she's not having any of that nonsense. She probably suspects another trap or similar horrible fate. She eats straight from my hand now, and she's very sweet and gentle about it. Corn is her favorite, but I know I can't give her too much of that. She licks my fingers clean and even puts her front paws on my hand so she can reach further back to search for other tidbits.


Too much corn makes a ratty fatty.

As completely comfortable as she has grown to being hand fed, she won't let me touch her. I'm disappointed by this; I love petting animals. I make cats and dogs melt in my lap. But the Force is strong in this poor little vermin, and her instincts run way too deep.

Most of the time, she seems content, even happy, but I'm not so deluded that I believe her #1 yearning is for anything other than freedom. So I've resigned myself to a rat's lifetime of obligation, and none of the love.

I named her Rita, after Rita Hayworth, who played indirect roles in The Shawshank Redemption via classic movies and wall posters. Shawshank was about prison, the rat in sort of a prison, so...Rita. That, and since rats can learn their names, I thought it would be an easy one for her to catch.

The fact that her name is an anagram of "I, Rat" is just a bonus.

She stars in my first YouTube video: https://www.youtube.com/watch?v=_QFW1QVWbIc

The next one will be better. I have plenty of footage; she's been a wellspring of weird rodent behavior.

Nanashi7,

Your point is thoughtful and logical and may very well be more on target than off the mark...

But when my part wild brown rat went native she adapted to the outdoors very well, her indoor skills had her invading neighbor's houses to steal food and her outdoor skills born from instinct made her a force to be reckoned with. She was a supreme indoor/outdoor suburban rat. Remember, for these wood rats, being free might just involve invading someone else's wood shop and stealing their stuff combined with the basic instincts to not get eaten, they may actually do better than rats that never lived with humans. Where I would agree that a lion that never learned to hunt might be disadvantaged being set free in the wilderness, my experience with our part wild rat would seem to prove that rats benefit from all of their experiences and adapt to survive.

Especially for brown rats, when we talk about wild, we might be talking about living in a warehouse or behind a McDonalds and foraging for native foods might be dumpster diving. Or in the case of my part wild rat, stealing my neighbor's dog food from his pitbull terriers.

We don't really know enough about wood rats to know if they can be released... if you think about it, all you have to do to return them into their native environment is to set them free in the shop.

As to the part about solitary wild animals kicking their kids out violently... bunnies tend to be pretty solitary in the wild too, but my friend had 17 at one time and they didn't kill each other. You may be very much right, or not... we can't disagree here because we won't know what happens until it happens.

In all reality, wood rats aren't rats as we know them... Some folks didn't think black rats could become true shoulder rats. And very likely some, many or most can't. But one did. Again we don't know much about wood rats in a domestic situation. We don't know if they can bond with humans or not... But folks have kept mice, hamsters, gerbils, ground hogs, beavers, nutria rats, pouched rats squirrels and even capybara's as pets and all of those have bonded with their humans... so I wouldn't bet against it yet.

It seems that most folks say that hamsters aren't social animals, and yet they have found a place in human households... But wood rats aren't hamsters nor are they black or brown rats... we simply don't know what we don't know.

For now, I think Rita is lucky to have found Kucero and not to have been trapped or poisoned. And I think he's really trying to take care of them. There's no telling where this is going to go... This could go terribly wrong or we may wind up welcoming a brand new species into the rat fancy...

For now, everything seems under control... and Kucero has assured me he is going to work on socializing his rat family so they won't wind up as caged prisoners... Which is a heck of a commitment when starting out with a wild rat of any kind.

For now.... I'm hoping for the best. If wood rats are as intelligent and emotionally balanced as brown and black rats a rat with a good temperament and an 8 year life span might actually have a place in this fancy.... But we will never know until someone seriously tries...

Our Max is only a year old and she's already starting to get lumpy, the constant cycle of rats dying off can't possibly be good for my eight year old daughter, even though they make for perfect pets and friends... If wood rats can be socialized and can live with humans in a family structure other than as caged animals, having the same rat for more than two years might be something I would consider seriously.

Although for now, I wouldn't encourage anyone else to try and trap a pet wood rat for themselves, I'm more than curious to see how this goes. There are some real challenges ahead, especially if one of the pups is a boy... But until things actually start going wrong... I'm going to stay optimistic... Lets cross one bridge at a time as we get there.

Things got worse before they got better. The day the vermin twins were born, Rita seemed tense. The following day, I guess the reality of her new role started setting in, and she began agressively lunging toward anything that moved. On Day 3, she was wound tighter than a deer streaking across a firing range. My hand doesn't go into that cage unless I'm offering food. I covered a finger in some delicious cream alfredo sauce I thought she'd like, and she lunged so violently, she overshot and made a mess all over her head. She spent a few minutes cleaning herself while I waited patiently with my hand as motionless as possible, then came back to partake of the treat the right way.

The problem is her vision, and it doesn't matter what kind of lighting is involved. The poor thing can't see. I usually keep it pretty dark, for the comfort of her and the babies, but she doesn't see my hand until it's about eight inches from the little bed she and the ratlings stay in.

As a precursor to feeding time, I say her name and click twice before releasing the latch that holds the door closed. On Day 4, she did a complete 180. Not a single lunge all day, no hesitation, and she's back to taking those edible tidbits as sweetly and gently as she always has. It seems that the best illumination is having a light source shine on my hand while keeping her in relative darkness.

Another positive change is that she's more comfortable cleaning and grooming the babies. Until Day 4, she would hover over them and conceal them as much as possible. Today, I was treated several times to the sight of two squirming babies getting baths while they squeaked and grunted in protest.

Aw man, I started getting really tense there for a minute but then when you said Rita did a complete 180 I breathed again. So happy to hear it:) that's a really good sign. You probably already know more about this little wood rat than anyone else and you obviously also have very good instinct. Rita's probably relaxed more into her role as mom which is awesome. Can't wait to see more pics.
 
#71 ·
How's this one? I took it only ten minutes ago. I forgot the flash was on when I took it, though, so I left them alone after that. Rita didn't seem to even notice. She was too focused on cleaning that baby's foot.



See all that white stuff? That used to be several cotton balls.
 
#76 ·
We have that hamster cage and used it temporarily as a home for my girl Cricket before we introduced her to her cage mates. I'm just so surprised and how...big yet tiny Rita is! She seems to have a very big head. Like a little cartoon. It is adorable, and if they really live that long, and can be social and friendly with people, I agree with Rat Daddy, might be nice new species to the fancy. Course that would take years, but hey, time breeds better results?

Anyway, that video is just adorable! and the pictures. and Rita. and the pups.
 
#77 ·
Kucero, that was the cutest thing I've seen in a long time:) firstly Rita with her baby's foot and the video. She she's so full of energy and has the biggest eyes and I love your little trash bins for new stuff for her to redecorate with. One of my rats is always trying to get into the garbage so you've given me an idea. And my other boy just after cleaning his cage he also does the whole redecorate thing. It's so entertaining to watch him. Thanks for the pics and the video really enjoy them. :)
 
#78 ·
So entertaining!! I can see how you fell in love with those big brown eyes!!

Your next video should be accompanied by Van Morrison's Brown Eyed Girl!!!

This is so interesting. I posted a topic a long time ago about domesticating rats, all in theory of course.
I'm going to be stalking this post for as log as possible! I'm like RatDaddy on the matter of experimentation and getting to observe this species in a captive setting.
The video with her in the blue hut was so cute <33

9-7-14 (First baby day)


9-8-14 (One day old)


9-11-14


9-12-14 (almost 5 days old)

For four days, Rita sat on her kids in the little blue bed on the bottom level. I don't know why she switched nursery locations, but now they're all crammed in the blue hut up top that Rita can barely squeeze her own self into. The babies about the same size as the first two little ones were when my neighbor found them, maybe even a bit bigger. Should we start a pool to see how long she'll keep them there before she decides that being a family of sardines isn't as glamorous as she originally anticipated?
 
#84 ·
Oddly, I've seen this in mice a few days after giving birth in a next they build with great effort, moms often move their pups to the most cramped space they can find in the cage. I'm thinking they start worrying about the babies crawling away on their own.

There may also be some advantages in nature in moving your nest to tighter quarters before predators find it.

Just a guess...
 
#85 ·
They'd have had a harder time crawling over the little bed's borders. It's so cramped in that hut, I occasionally see a baby hanging halfway out, little feet just a-kickin'.

Rita can't even get her entire head out in the open. Feeding her is much more difficult now because it's not only difficult for me to maneuver from the cage opening to where I have the hut bolted down, but since she can't lift her head, I have to bring my hand all the way to her until my fingers are almost beneath her nose. This makes me a little nervous because of proximity to the babies...I've had little tails and little feet press against me...but Rita hasn't given me any warning lunges or even indicated that she's nervous. To the contrary, she occasionally takes her sweet time during bites, pausing to groom herself or a wriggling baby before acknowledging whatever tidbit I'm patiently holding for her.

I don't mind it one bit. Grooming and cleaning isn't something she did at all during those first couple of days, so I think its a positive sign.

Glad to see someone else take care of a caught wild rat :D

I have a wild albino rat that a friend caught running down the street... somehow...

They make for... very interesting pets. Don't really know if shes fully wild or someones former pet rat, she isn't scared of humans nor was she ever to began with. When I first met her (a day after she was caught) she straight away licked my entire hand. She doesn't like being held though.

Albinism is a mutation that does occur in the wild, but any wild rat unfortunate enough to live with it won't do so for long because white rats are REALLY obvious to predators. And although the sum of my rat knowledge comes solely from a few weeks of reading plus my experience with my own little wild pest, I'm 99% certain that no adult wild rat who has not been tamed would not be afraid of humans. It sounds like your rat is domesticated.

Day 6 - Rita is still keeping the family in that cramped one-room apart-hut. At the rate the babies are growing, she's going to have to relocate back downstairs really soon, before they're too big to fit through the upstairs/downstairs porthole.




It might look like levitation, but this little one is just "hanging out". Couldn't resist. :)




I'm really glad I got these last two. Toward the day's end, Rita tried something new, putting her head against the back wall of the hut, her hindquarters at the front door, and turned to lay mostly on her side so the little ones could easily find a nipple and latch on. This is the first head shot I've been able to snag since the one I got away with on their first full day.



And here they are, both of them content and happy, and it looks like the ears are beginning to unfold. Evey resource I read from said this shouldn't happen yet, it's supposed to happen on the 9th day. Whatever the case, they sound healthy (I love all of their little squeaks!), they are uncoordinated but energetic, and they look beautiful.

AznDonutBoy...

First, being white or even albino is not a fatal handicap for a wild rat. I've seen captive raised snakes for example that only eat white mice and my best fishing lure was a dark green Rebel painted to look like a small pickerel. It worked in both fresh and salt water. Predators are looking for a certain color/shape pattern and white isn't likely what they are expecting to find.
Secondly wild rats tend to burrow and move rapidly from one sheltered location to another as well as using shadows to their full benefit. Thus they wouldn't be exposing their white fur to present a target very often or for very long. I do however believe that the poorer eyesight commonly associated with being albino would be a handicap depending on where the wild rat lives.

This also becomes a point of interest... because when we say wild rat... we aren't talking about giraffes we are talking about rats... Rats don't free range the vast plains of Africa and graze treetops with their long necks or stampede across the open plains like Wildebeest or Zebras. A wild rat might live in a warehouse or under a schoolyard playground or under a McDonalds dumpster or in a landfill... To a wild rat the "wilderness" may not look very wild to us. A white rat in a landfill full of waste paper products may be very well camouflaged and living in a warehouse might present no challenge at all for even a blind rat that learns it's way around be feel and scent and to avoid forklifts. The first albino rat was found in a cemetery... perhaps marble or cement tombstones also being white might have even given the albino an advantage.

Nonlethal genetic mutations occur over the course of centuries or even millennia, I suspect that most of the genes that provide the broad color and pattern palate have been around for a very long time. As they are recessive they aren't often seen in wild populations, but I'm guessing that there were some very rare hooded rats, for example, around long before humans bred for this trait and that they were successful in passing on their genes.

All of that said... I agree that your feral albino was a most likely a domestic rat that was released at one point. Adult wild rats are notoriously difficult to socialize. This isn't because they can't be socialized or that they can't bond with humans. It's just that wild rats tend to defend themselves and have a strong fear response when taken captive. Combined with sharp teeth, speed and agility this usually means the human is going to get really hurt before and during the bonding process.

A few years back, my daughter found a pack of wild rats free ranging in the zoo parking lot, she was 5 years old and wanted another rat, she already smelled like out girl rat and when she went into the shrubs to "catch" herself a friend for her rat, I was astonished to see the wild rats respond very playfully, darting around her feet tempting my daughter to chase them and then dashing off into the bushes and rather than being chased off, more and more rats came out to play... until there were actually so many smallish wild rats darting back and forth that I realized my daughter's chances of actually grabbing one were getting all too good for my liking and I ended the play session... I'm substantially certain that if she actually grabbed one of these wild rats it would have been game over and things would have turned bloody serious instantly. And I'm not sure if she might not have gotten attacked by the pack or just bitten by the one rat she snagged. As a dad, this is one experiment I wasn't up for. It was crazy enough to let a 5 year old chase around with a pack of rats in the first place, even when I'm pretty good understanding rats and they weren't being aggressive.

Nothing is completely certain, but I'm guessing if you grab an adult wild rat that has had no human contact, you are going to get bitten 99.99% of the time. So, if nothing else, I base my opinion on that....

I also believe that most rats still have some latent wild abilities that a stint in nature will bring out so a domestic rat is going to develop it's skills by being outdoors over time. Our Fuzzy Rat could navigate vast distances outdoors. Max learned to find the car after several outings too. This kind of skill simply isn't something indoor rats develop, so I'm not at all surprised that your albino is a very interesting rat. And yes, it might be a recent wild rat back cross, like my part wild rat was. Accidental or even intentional wild x domestic crosses happen and although the vast majority of first generation wild crosses look wild second, third or subsequent generations are likely to look like a domestic rats, but aren't necessarily going to act like domestic rats, hence it was set free or escaped. So if your albino really does act wild, it may be the result of a recent back cross... but if it didn't bite you, I'll bet it has had some human contact before your friend caught it.

The world is full of some very interesting rats!

As to the subject thread, the pups do look great and it's really nice that Rita isn't freaking out around you. Every day we add something new to our knowledge-base.

My mom told me stories about her pet squirrel that she hand raised before I was born eventually she set it free to live in the Oak tree in the back yard, but she said it always came into the kitchen for breakfast with her and it would often follow her around the house while she did her chores "like a puppy" until they sold the house and moved. That was about sixty plus years ago... and even before that, squirrels had been kept as pets as the term "squirrel cage fan" obviously comes from somewhere. So I don't doubt that wood rats have been kept as pets by someone before too, but most of the information folks gathered in their homes based on their actual experiences have been lost. The nice part of you actually doing this now and basically live and on line is that we are all learning with you and creating a record of actual fact, not second hand recollections from the son of someone that did something 60 years ago that is no longer with us to fill in the details.

Over the thousands of years of human experience science was done by everyday people. Everyone tried stuff and when it worked we learned and progressed. Now we've relegated research to a few researchers... which I find very sad. I'm thinking if the human race had assigned scientific research to a few research specialists thousands of years ago, we'd still be reading research papers on the potential of creating heat from fire off of sun dried clay tablets.

You are really doing good work here and I remain fascinated with where this will go. A domesticated rat that lives 8 years would most certainly find a good home in my household... As much as I love brown rats my daughter has lost 4 best friends in three years, that's a whole lot of loss for an 8 year old to have already experienced.

Friends who don't object to rats are telling me that this can't be good... and the other day when I brought up rats that live longer, my daughter said that might not be good because she might get too attached... Are 8 year old kids supposed to be worrying about getting too attached to their pets? I don't know the answer... but I'm getting concerned.

I don't know if wood rats can become human companions, and lord knows I like my fancy pens and don't want them wandering off, but I've got an open mind and thanks for sharing your adventures with us. I can't wait until the socialization and bonding phase gets into high gear...

Best luck.
