For 20 something years, my male & female (a year older) older cats who were neutered & spayed for about 17 years. My female cat has now started to do number 2 on the floor over in the corner floor areas around the litter box. I don’t get it? Why now after All these years? How can I stop this? If I get another litter box, he will have to use it as well. And I can’t keep them in a room apart (that would be cruel) – they’ve had the run of the house for 26 years. I’d appreciate the help. Oh! The only real thing that has changed has been that our dog died (we took him outside to potty ). I’m wondering what’s going on & how to stop this? Thank you.
