Some of you may remember my post about 6 months ago about rescuing a cat which was neglected. Well, we're doing well, all cats are friends now and she's happy. I just have trouble with her biting. She comes to me for petting (nuzzles into my hand and sits right on me) and all of a sudden, out of nowhere she will just bite and scratch me. There are no warning signs, no noises she makes, no ear or tail movements - one second she can be absolutely fine then the next she just lashes out. I've been to the vets and they can't tell anything is wrong to make her act like this - are some cats just like this? She has never once tried to bite my 5yo son or my 4yo brother, it just seems to be adults. I want her to stop, it's not really a big deal if I can't as I just don't stroke her but then I feel so bad as she looks at me longingly and goes in between my phone and my hands, she really wants to be stroked but then one second later she just attacks me! I have scars all over my hands and arms from this. Any ideas?
