It sounds like you’ve had a lot of animals and none has given you this trouble before. In all the years and all the dogs and cats we’ve had, we’ve only had two neurotic animals and they were both dogs. OK, three dogs. I forgot Sadie. I’m not at peace with the decisions we made with any of the three. I won’t go into details. But we did the best we could with what we were able to do at the time. It’s in the past and I won’t grieve about it. One suggestion that I haven’t heard regarding cats - there is a large contingent of people who post on kitty ping who think that cats cannot be allowed to be outside. I have always had a cat but never one who was not allowed outside whenever he/she wanted outside. I’ve never had a neurotic cat. I’ve never had a cat pee or poop inside. I don’t even have a cat box for the one I have now. He just waits and goes outside. Much healthier for all concerned.
It’s been my experience the prime desire to keep a cat indoors always is longevity (getting hit by car, fights with cats/dogs, exposure to disease). Cats are territorial and natural hunters. Some cats do much better outside.
