We discourage the use of store bought "rabbit cages". They are all too small and usually very hard to maintain/clean. Rabbits need space! We highly recommend a puppy exercise pen (left photo) or a homemade condo (right photo). We have found the exercise pens to be the easiest and it's what we use in our rescue. It provides enough space for your rabbit to binky, stretch, and stand on his hind legs. Of course time out of their housing is still very imperative! If you have a jumper, we recommend a taller pen or you can purchase a cover. Please let us know if you have any questions.
