It can be pretty dangerous to allow whole house free-roam because of things such as ovens, tiny cracks that your rats might sleep in, wires, items falling on the floor, etc.

Also, I have this bag that my Vans came in and I was wondering if it would be safe to put it in my rat's cage as a large snuggle sack with fleece strips in it.

Sure!

 

Thx so much!

 

I feel like it might be okay ONLY if you watch them and make sure they aren’t able to get under stuff (like ovens)

 

I've read of people's homes flooding because their rat chewed through a washing machine hose. Rats can be really destructive and sometimes they're sneaky about it.

I used to let my rats free roam in an old apartment. I thought they were being good but when I moved out, I found all of their hidden potty spots and where they had been chewing on the built-in woodwork. I wasn't pleased.

Allowing your rats full free-roam might work well for you and your particular rats but you'll want to be very, very careful to prevent them from getting into stuff that they shouldn't and potentially be prepared for some damage to your property/possessions.

 

They have a horrible habit of biting into tubes & plastics containing gels/liquids. Tooth paste, sunblock, paint, ant bait traps, super glue.... it's worse when they are thirsty & won't go to their cage for water - but it's not even about the hydration. They like squishy objects and WILL climb into drawers/counters & poke into them for taste.

 

Don't even think about letting your rats float free. In case you like unpleasant surprises, you can let your pets out. And surprises can be not only in the form of chewed wires. Rats are very agile creatures. They can climb where you can't even guess. The fact that a rat can just run away isn't the worst thing. They can carry disease with them. It's possible to set up a separate room for the rat with escape protection. But your layout must allow you to do so. You can explore this site https://www.boutiquehomeplans.com/cost-to-build.
