We have an 11 year old cat who acts like she wants to be petted as she's all affectionate when she rubs up against you and you reach down and pet her but when she has enough of petting she reaches out to bite you. She won't let you touch her underside either and she bites like she's trying to play? I don't know. She might have been abused, she doesn't jump up on the furniture either because I think someone was mean to her when they tried to get her off of it or 'train her' about staying off.
Make sure she's not in pain. My 10 year old cat just developed arthritis in her back and if you touch a spot on her back, she will attack/bite really hard that's out of character for her. I give her glucosamine now, so it happens way less often. She was evaluated by a vet who determined the pain was on her back near the tail.
But, some cats just don't like being petted or being petted long. They can get overstimulated and petting can actually hurt...too many nerves I guess.
Was she ferel at one point?
I tried to condition-train her with treats and lure her onto my the sofa by telling her it's okay to stay there, but she wont really go on it much and I tried playing with her and THEN petting her but she still nips. She wags her tail like a dog - not aggressively or like she's marking her t
This is exactly like Cersei, who I recently rescued. She still wags her tail -- very anxious --- won't cuddle at all and ducks when I try to pet her. She used to bite, but I trained her with treats so she doesn't bite or growl at us any more.
She's at my grandparents house cause my dad's allergic. I try to be nice to her, yet again, she only bites. Anything I can do to stop this?
Watch as many episodes of Jackson Galaxy's My Cat from Hell as you can. You will learn a lot. Every time you to visit your grandparents, give her a treat as soon as you walk in the door. Don't force physical contact.
