I just wanted to come back and tell everyone what I had to do to remedy the problem cat.
Took the cat to the vet, and asked him, as a last resort what to do. I hate putting down a perfectly good animal, but i was at my wits end.
We tested him for a UTI and it came back negative. so the vet said it's a behavioral problem. He said prozac would be the thing to try next, said that they've had great results with prozac and cats with behavior problems.
Fist night on prozac he stopped peeing in front of the child's door, stopped peeing under the high chair. and stopped howling at night. He's much more mellow and he comes out more than he used to during the day. My only issue is it's stressful to me to give him a pill everyday. Can't mix it into the food, he smells it and tastes it. Anyway, things have been much better since he's been on prozac.
Wish it didn't have to be like that but he's still alive and still with us.
thanks for all the input.
Larry
