About a month ago, I got my bun a new c&c grid cage instead of the other small cage he had. He used to have super good litter box habits, all until I got the new cage. I tried everything, literally. And every day is just a big hassle to clean out his cage because there are poops. Everywhere. He was never like this before? I don’t even need to clean out the litter box because he never uses it, at all. Maybe an occasional pee here and there, but never poops. The only time he will step in his litter box is for water and hay. Help ???
