What do you people house rabbits in? For indoor pets, I like Living World cages. Easy to clean, sturdy, and compact. Though Willow currently lives in a small kiddie pool she can jump in and out of at will. It works well because the aging guinea pig that shares it can't clear the walls, but gives a springy thing like a rabbit no issue coming and going. They're good friends, and I find it far more space efficient to have them share housing, as basement space is limited.
