2 months ago, we got our cute little rescue cat when she was 10 months old from our local vet. We already have another 2-year old cat as well. However, our new cat keeps having problems with pooping in the box! We have two boxes, one is the pellet-based Breeze system that she seems to prefer. It has walls but no roof. The other is a covered box that uses clumping litter. Our other cat prefers that one. The new cat has used both for poop, but seems to prefer the Breeze if she uses a box at all. She is constantly pooping outside of the box on the carpet. She even pooped in the shower once about a month ago, and then rubbed her butt on the floor, so we finally took her to the vet and all they did was express her anal glands which were apparently full. However, this has not helped her pooping problem. The vet tech did not have any advice for us, other than that it might just be a strange quirk of hers. We also tried changing her food to a sensitive systems food, to no avail. Please help!!!
