When I took him he was affectionate, sweet, attention hungry. He has shown zero aggression through doors and screen doors towards my other pets. I slept in his room on night one. I got out of bed to shut the window and then went to get back into bed, he attacked, grabbed onto my back with all claws. He stopped quickly and sat there. I went to pet him and he grabbed my arm and bit hard. I turned my back to him and slowly lowered into bed. A few min. later he came up to me purring and rubbing on me, so I pet him again, only to be attacked again. Left the room that time! The next morning he was fine, and that night went so well I was able to cut his nails, but the next morning I was again attacked. Any ideas what this sounds more like; Behavioral, hormonal, or stress?? Will neutering him help if he's an adult and it's hormonal?? en-us Copyright Catster 2013 Tue, 21 May 2013 18:47:52 GMT Tue, May 21st 2013, 11:47 GMT http://blogs.law.harvard.edu/tech/rss Catster.com catsters@catster.com catsters@catster.com http://www.catster.com/answers/question/adopted_unneutered_adult_cat_into_a_6_cat_home_all_fixed_no_aggression_towards_other_pets_so_why_tow-58785#answer-163153 Neutering is the thing to do for a bunch of reasons. It may calm him down, but from what you've said, this poor little guy has lived in hell for a while. If it were me, I'd give him his space until he decides for himself that you're OK. Cat attacks can be vicious and you could wind up in the emergency rooom. Don't attempt to sleep in his room. Talk to him, play with him if he'll tolerate it, but don't try to pick him up or force "face time" with him. Let him call the shots. And speaking of which, get him to the vet as soon as you can to make sure he has no health issues that could be passed to your other cats...the least of which could be fleas. Explain to the vet you're cat's somewhat "manic" behavior and ask for their advice. Good luck!
