A pet rabbit should be housed inside. He’s a social animal, and he'll wants to be near his people. Provide him a cage that’s at least 4 feet wide and 2 feet tall. A larger cage is even better. Avoid wire-bottom cages, which can cut his feet. Line the bottom of the cage with straw to make it soft and warm. Bunnies are prone to overheating and can die if left in the sun. Never leave your bunny rabbit in a sunroom, car or enclosure.
Let your bunny play and exercise in the house, but keep a close eye on him, particularly while he’s young. A rabbit may chew on electrical cords or pull lamps down. A bunny can also destroy furniture, flooring and woodwork by chewing, scratching or soiling. For unsupervised play outside his cage, provide a pet rabbit with a safe, rabbit-proof room. Never leave him outdoors to play -- he could become prey for neighborhood cats and dogs, wildlife or large predatory birds.
