Hi Chris. Congratulations on your new bunny!

I don't know much about them, but I think if you leave him/her in the bathroom, or any other room, it might chew up a lot of stuff. Besides, if bunnies are anything like guinea pigs and hamsters, they like to have a little safe haven where they can hide and sleep.

I'm just guessing here, and I hope someone smarter than I will correct me if I'm wrong.

Good luck!
