Your rabbits' cage should allow for plenty of movement. The size of the cage will depend on the size and number of rabbits. In general, giant breeds (greater than 12 pounds) require a minimum of 30-by-36 inches to 36-by-48 inches, medium breeds (7 to 12 pounds) require 24-by-30 inches to 30-by-36 inches, and smaller breeds can be accommodated by 18-by-24 inches.
Some sources report that no matter the size of the rabbit, they should be confined to a space no smaller than 4 feet long, 2 feet wide, and 4 feet tall, or a minimum of 12 square feet. In general, the bigger the cage, the better!
They should be able to hop at least three to four full hops in each direction and fully stand on their hind legs without touching the top of their cage. Often, commercially available rabbit cages are too small. We recommend getting creative and making your own.
Solid floor bottoms are preferred over wire mesh bottoms to prevent irritation to your rabbits’ feet. The flooring should be covered with absorbent material. Unscented pelleted or shredded paper bedding, along with fleece material, can be used with care to avoid cedar or pine shavings. Soiled bedding, including their litterbox, should be removed or cleaned daily. Cages should be cleaned at least weekly with soap and water or a dilute bleach solution (1:10 ratio). Always rinse thoroughly.
Your rabbit should also have a designated exercise area. You can use fencing panels and tie or pin them together, as well as puppy playpens or commercially available exercise pens. Make sure there is non-slip flooring. The height of the panel should be at least 3 to 4 feet, depending on the size and breed of your rabbit. If you are going to let your rabbit roam freely, then you need to bunny-proof their environment (Google bunny-proofing your home for more information). In either case, you should never leave your rabbit unsupervised, especially with other pets in the household.
