My rats also hate water. Odin will claw me to death during baths but he has bad skin due to a fat gene or something like that. My vet said lots of big rats have bad crusty skin D: Poor Odin. Yeah so because of those crusties I have to bathe him. I've also tried giving him Omega-3 oils to help.
I use baby shampoo or kitten shampoo. My guys love their baths though because I have started them out early with it. Iriquois dives into the wtaer as soon as I am even close to the tub. I bathe them twice a month sometimes more.
every rat I've had HATES baths. I use a shampoo I found at the petstore called "pet sensations small animal shampoo" they make her smell really nice they come in "cucumber melon" and "Raspberry" o.o
they both make my rat smell so good X3
I must be pretty lucky because my Nazy just sits in the sink and takes his bath. Wanna know whats wierd? he even BOOGLES!!! I'll take a vedio some time. I don't think he knows he's a rat lol. I gave all the babies baths as well to get them use to it so maybe they wont hate it as much. It went well . I use a Bunny shampoo that I also use for my bunny . Or else baby shampoo if I don't have my bunny shampoo.
