Hello. I've decided that my ferrets need a bigger cage. Since my father use to build rabbit cages, and it looks cheaper to build one, I've decided to give it a try. But before I do so, I wanted to know if anyone had any suggestions. I've been looking at other ferret cages, and have noticed things like, some doors open side to side, others open top to bottom. Does anyone have preferences? Do your ferrets enjoy shelfs that go only half of the cage? Should I build it where all levels completely cover the level (except the hole for the ramp)? I guess I'm just looking to see if anyone has any insights or advice. "My ferret loves..." "I find it easier to clean when..." Thanks, Kalee [Posted in FML issue 3373]
