I have an eight year old that that has become quite the problem cat. She is spayed, healthy and affectionate. I have over 20 years of cat ownership experience. The problem is urinating outside the box, and only in the family room. Yet she always poops in the litter box. This started a few months ago when we could smell cat pee but wasn't sure where it was from. Then we caught her peeing right under the dining room table. I took her to the vet the following Monday and they said nothing was wrong with her. I cleaned every stain I could find got two additional litter boxes, one of those pheromone diffusers and the problem has only gotten worse.
Recently I had the carpet professionally cleaned to remove pet stains which cost hundreds of dollars. Then last night I stayed up almost all night to watch the cat, she started sniffing around her favorite pee spots, every time I would pick her up and put her in a litter box (all of them clean). She would never use it. After about five rounds of this she started standing next to the front door. I let her out. We live in a condo so she was just out in the hallway. Which is carpeted and it is easy to get outside into the grounds. She just stayed next to the front door. I check on her in two hours and she is still by the door. She wants to come in. Immediately she starts sniffing around where she tends to pee. I put her in the litter box again! Then maybe fifteen minutes later when I’m not paying attention she pees on the carpet! I spot her mid-stream and she darts out of the room knowing she is deep trouble.
I’m at my wits end; I cannot tolerate living in a house that smells like cat piss, and this cat is so suborn she would rather pee on my family room carpet instead of outside or the box! I would have considered the hallway carpet a small victory. I think my choices left are, keep her in a cage with a litter box, Give her away (if I can find any takers), turn her into the animal shelter, or euthanasia. We are very strongly considering the last option.
Anyone have any ideas beyond these?
