Rabbits do not need a cage - they can be house bunnies, like Miss Hoppy, if you are willing to take the proper steps to bunny-proof your house. She has a cage - it's a two-level ferret cage, actual, and that is where her litter box is. They can be very easy to litter-box train, Miss Hoppy was. She sometimes hangs out on the top level of the cage, which brings her closer to our eye-level.

I have never ever heard of a rabbit living to be 30. The current estimate of lifespan for a well-cared-for indoor rabbit is 8-12 years.

Rabbits should absolutely be spayed or neuetered - that no only helps curb behavior problems that are hormone-driven, but prevents certain cancers, depending on gender.

Rabbits do not need to eat pellets, though many do quite happily. Miss Hoppy has lived on just greens, veggies and hay since we got her.
