My Mother-in-law adopted a cat from some friend who were not able to care for the way he needed about one year ago. He is 10 years old and very obese.
A month or two after she got him, he started pooping on the floor. Some times he will go in the litter box, but a few times a week he poops in random places in the house, and he never pees on the floor.
She is very good at keeping the litter clean, she cleans it every day, sometimes twice. It is also in a safe spot so he cant be ambushed by anything or anyone.
We are not sure what to do to stop it. Can someone give me a hand.
