when I groom him with a brush he loves it, closes his eyes and purrs but all of a sudden he gets angry and grabs my hand and bites and scratches which hurts! I use a wheel chair which he loves to sit in when I am not using it. That is ok with me until I need my chair. I approach him quietly and gently but he gets upset and sometimes tries to bite me. I gently push him off, not harshly. Usually he allows me to pet him but no way can I pick him up-he won't allow that, he will bite if I try. I don't try any more.
At bedtime when I lay down he politely crawls up on my chest and I pet him for about 3-5 minutes which he loves. When I'm done he jumps off and walks way. this is the only nice time we have together. I have never had a cat who was as angry deep down as Sammy is. We got him from a shelter, about 2 months old and have given him lots of love and toys and done everything we can do to allow him to trust us. My husband is giving him too much cat food in an effort to make him happy. He is getting a little pudgy (the cat, I mean!) He is well cared for by our vet and is physically very healthy.
I say he has tantrums because if things aren't exactly as he likes them he growls and runs away showing his displeasure. He does get over these spells quickly.
He doesn't do it randomly. he has done it since about 3 months-yes-neutered
