My cat has had problems with using # 2 in the litter box, when my mother moved away with her cat who was pretty much the "king" of the house went with her, my cat stopped going outside the litter unless it was too dirty for him . I had just moved into a new home a few months ago..and i noticed about a month and half after we moved in, he started peeing outside the litter. he had no infections and plus he knew what he was doing because he would take off and hide after he did it even if i wasnt there to catch him or notice it. he did it a lot more when i had to cut back his food due to him being extremely overweight but i found ways to let him think there was enough food in the container so he didnt do it as much . i have tried being nice and telling him no ..also i have done the water bottle and putting him next to the spot and telling him no . im too afraid to tap his nose or anything due to him being abused by previous owner. I NEED HELPPPP !!!!
