answer:Just be patient and calm around her. Trying to chase after her or being too aggressive in attempting to earn her affection will be almost guaranteed have the opposite effect. If she has already seen a vet and been treated for fleas/parasites, tested for FIV/FeLV, and given a clean bill of health.. that’s the biggie. Having a healthy cat is definitely the first step to having a happy cat. You should start to develop a small routine with the cat to earn her trust. If you haven’t already, you should purchase a package of kitty treats. Try shaking the container that it comes it (bag or a canister shouldn’t matter, they all rustle or rattle). If she isn’t comfortable taking a treat from you, or even close to you, start by setting them a bit away from you until you find a place that she is comfortable with. Of course, as days go by, slowly move the treat closer to you. When/if you ultimately get to the point where she is willing to take the treat from you, try petting her. Just go slow. Eventually you should earn her trust where the treats will be unnecessary (and just treats for special occasions). It sounds as though she is already acclimated to being around people. She isn’t hiding, she isn’t hissing or crouched in a corner looking mortified. That’s a good sign. I would say that you just need to give her time. Have you actually tried to pet her? If you are afraid and go jumping all around her, you will make her afraid, as well. If you’re calm and approach her she should be fine. Worst case scenario is that she will run away. Cats, in my experience, are not like dogs when it comes to threats. The cat is more likely to run away as fast as their legs will carry them before they will snap at you. I would just avoid picking her up. Hope that was helpful, I know most post was a little bit all over the place.
