Hello, I have a male cat that I've had for 2yrs. I found him outside. From the time I got him he was always a very frisky cat but very aggressive. He has been pooping in my tub for about a yr now maybe longer. I changed cat litter from regular to clump and seal. He still goes in the tub. I bought a covering box. He still goes in the tub. I bought a uncovered box he still poops in the tub. I started leaving the shower on so he wouldn't go in the tub and he pooped on the side of my toilet. I don't know what to do to get him to stop. This is a routine for him. Please help
