I have a friend who has an ongoing problem with his cat, Fred. We've all heard of cats marking the house by urinating, which is a horrendous problem. But this cat...shits. Everywhere but in his cat box. And it's usually very loose...i.e. diarhhea. The cat shits on the guy's bed. On his couch. On his clothes. Even got up on top of the refrigerator once and shit down the side of it. Every day, it's not just a once in a while thing. I don't think most people would put up with this, but my friend cannot bring himself to put the cat down or give him away. The cat pees in his cat box just fine, he does not pee around the house, only poop. There is one other cat in the house, and that cat uses the cat box and doesn't have a problem. My friend has tried everything...been to the vet many times. Tried vitamin B shots. Different cat litters, different foods. Different boxes. Putting the boxes in different places. The cat quit doing it once for almost a year and a half, but now it has started up again. Anyone had any experience with anything like this? To me it's obviously some kind of physical problem, but why can't the freaking vets figure it out?
