he has 2 chew toys in his cage. I will put a litter box in for sure. there is a shelve that goes in the cage but I took it out when another rabbit kept peein on it
I would just throw a piece of cardboard inside a pillow case and throw that down. Itt's what I have covering my bunny's level and it's easy to wash/replace as needed. Also maybe a cat ball, or hanging bird toy? something that makes sound and can be moved and played with.
I have a cat treat ball that I fill with rabbit treats (Craisins, dried blueberries, veggie puffs) and he has to roll the ball around in order to get the treats to fall out of the holes.
Looks just like this, but blue. I got mine from a dollar store.
