I'm a new owner of two 8 week old female does, and I'm not sure if I should provide bedding for them. I've read on rabbit websites that bunnies love having some sort of bedding to arrange and sleep in, but when I tried lining the cage with hay, they just pooped and peed everywhere and it was really unhygienic, so I stopped that. In other threads, some people suggested putting the hay in a box, but they'll still confuse that with the litter box, right? Is there perhaps some sort of bedding I can use that they won't confuse for a pee-place?
