While you may believe the outdoors would be a natural place for a rabbit to live, domestic rabbits are only cousins to the ones you see in the wild, and are unable to live outdoors appily and healthily. Predators, temperature extremes, and parasites are just a few of the hazards facing a rabbit housed outside.
Rabbits need a minimum space that's four to six times their size, along with enough head room to stand on their hind feet. We recommend a space no smaller than 4 feet x 6 feet.
The enclosure should be large enough to contain a litter box, a hidey box, food and water bowls, toys, etc. and still have enough room to stretch out.
The rabbit's enclosure should be somewhere that's frequently visited. Avoid drafty or super-noisy areas. Rabbits are social and animals and enjoy being talked to or receiving a quick pat on the head as you pass by. Rabbits like to be housed where all the action is - where you spend the most time.
Why use an exercise pen and not a cage?
Much easier to clean (can sweep or vacuum floor and no wire bottoms to clean)
Easily reconfigured to include or exclude furniture, corners, and walls
No wire flooring! Wire flooring is uncomfortable for your rabbit, can easily cause sores on their feet, and
eventually may cause disfigured toes.
Cages are too small
Here are just a few examples of ideal rabbit enclosures:
