I think the cat I had been feeding for 6 months or so was already someone's pet....lost maybe or dumped. My neighbor and I trapped the cat. It is a black cat but when I took it to the vet it had already been altered. The vet clipped his ear I guess in case we decided to trap and release. He sits on my lap....but is very angry when I want to get up....growling and scratching. He does not like it when I move around. He stayed upstairs in the house for the first month...only came down when I went to bed. Now he moved into the office on the first floor he stays in there....sometimes he will come out and wants to sit on my lap. He gets in my face...drools and kneads my chest. He gets frightened easily and growls....I am trying very hard to be patient but cannot figure out how to get him off my lap without upsetting him. He is not a small cat and can be very intimidating. When I tried to pick him up he bit me....I expected that but not the aggressive behavior when I want to get up....ok he only needs the litter box twice a day I need it a little more. How do I handle this problem???? I really need some help from people who understand these cats. I do not want to give up.
