Suprisingly rabbits are a lot like cats. They don't like to be confined into tiny cages 24/7. They should be free to roam and trained to use a litter box, just like a cat. Hay, vegetables and friuts are the best things to feed your rabbit. Keep hard things, that are safe, for them to chew on to keep their teeth short. Rabbits can live more than 10 years but they are prone to types of reproductive cancers.
