I see all the time people trying to raise meat rabbits in a 24"x 24" cage. When I ask why the cage is so small they say that is what the ARBA recommends. There are two big fallacies with this. First of all this is a MINIMUM size, not a suggested size. Secondly, and by far the most important, is that this is the size for a SINGLE rabbit, a buck for instance, or a show rabbit. It is Not, Not, Not the size for a breeding doe. The absolute MINIMUM size for a meat doe that will be or is raising kits is 6 square feet (that means if your cage is 24" deep, they need to be THREE FEET wide.
If your does are over 11.5 pounds, that increases to 7.5 square feet.
