Just over a year ago my son adopted a 5 year old female rescue cat. She had been at the rescue place for a year. She wouldn't have been easy to rehome because she couldn't be with other pets or children and was known to be a bit - feisty. He decided that as he lives alone he would take her - I honestly think she would have still been there if he hadn't.
She took a while to settle in but eventually took to him and he is obviously her human - sits on his knee, seeks his presence (he works from home quite a lot). She doesn't like anyone else - won't let anyone approach her but occasionally approaches them. Doesn't want to be touched or picked up. Even he has a struggle to get her in her carrier to go to the vet and just once she had to go into a cattery and she really struggled. Fortunately it was only for 2 nights.
Every few weeks he has to go away overnight for work and I have to go and feed her and if she wants let her out. She doesn't have a cat flap. Usually I talk to her but don't otherwise approach her.
The thing is she seems to have a fear of people's hands - she has twice clawed/bitten me when I've not been interacting with her. Then she seems to remember this for months. She attacked me on Thursday for no reason I can understand but it was triggered by me picking something up. She was pleased to see my son return and wants to be in his company, but he reached for something and she did the same to him. It is frightening because although she is small, she is so vocal and ferocious - but she is obviously very scared of something and it is quite heartbreaking.
Apart from Feliway, has anyone got any suggestions.
