That looks, in my opinion, like a minimum size for a small to average adult bp. I think it would be too small for a 5-6', fat female. Even though they like to spend most of their time curled up in as tight a space as they can cram their bodies, they still need to spend SOME time stretching out and moving around to remain healthy. The mere 6" of depth bothers me, too...but I know that is not uncommon in breeding racks.
