Hi, one of my cats Nyska is really nervous. she flinches for every noise or sudden movements. I have had her since she was a little thing and has nver been abused, that is just her nature. The other two have no qualms about noise, movements, or new people coming in the house. Hopefully, nothing bad ever happened to your kitty, but if it did at least she is now in a safe environment where she is loved and taken care of.
