HI ladies...it's been a while since I've been on the boards but need some help. I have 6 cats of my own and 3 fosters. One of my cats has been pooping outside the litter box. It is mostly diarrhea/soft stool. Finally after weeks I caught the kitty who was doing it. It is my FIV+ foster. I took a stool sample to the vet and they said they could not find anything wrong. We only have carpet in two small bedrooms and that is where he is pooping. It seems he is still peeing in the litter box though. I clean it up with an enzymatic cleaner and scoop twice a day. Just yesterday, I caught my other foster pooping on the carpet too. I'm not sure if since she sees Miller doing it she has started to also. My thought is to put both of them in my master bathroom with Cat Attract litter to retrain them to poop in the litter box. My question is, how long do I keep them in the bathroom? I hate to switch all the litter to Cat Attract because it's so expensive. I have 4 litter boxes in the house and one on the screen porch.
