I'm kinda at the end of my rope here. My cat is 13 years old and has never once had litter box issues. Now he suddenly has started to randomly poop on the carpet by the front door. He has done it 3 times in the last month and there doesn't seem to be any method to his madness. I'm using the same litter, nothing has changed in the apartment, litter box is kept clean. In fact I just replaced the bag and added brand new litter last night then I wake up this morning to a mess in the same spot. One time he got on the counter and knocked my out going mail onto the floor then left one little tiny turd right on the envelope!! He checked out perfect at the vet they even did blood work and all that testing everything which cost me $180. The first two times it was while I was gone but last night it was while I was asleep. Today I got a carpet extracter and cleaned the carpet in that area really really good then soaked it with Natures Miracle. He doesn't pee on anything either but has been acting "different" than he used to. More weird and kind of mean biting my legs when I go anywhere especially when I'm going to bed and he's meowing way more than he used to. I don't know what else to do but I can't live with a cat that poops on my carpet it's disgusting and I refuse to be one of those cat people that has a house that smells like cat pee and poop with disgusting stained carpets. I saved his life when he was a kitten and he has had a great 13 years with me and been spoiled rotten with the best food etc etc but I will have no other option than to have him put to sleep if this continues. The pound or humane society are not options either he has been alone with me for all these years and all that would do is stress him out and pass the problem along to somebody else which isn't in his best intrests. Might seem cruel to some of you what I'm considering but it is what it is. Any other ideas for me or something I'm missing??? He can't become an outdoor cat as he has no front claws, not my doing, and the apts. I live in don't allow outside cats anyway.
