We have a 1 1/2 year old cat that we received from the humane society when she was 3 months old. Our cats behavior has changed considerably over the course of that time, she used to play and snuggle with us and visitors. I am not sure of any specific events that would of caused these behaviors over the course of that time. The situation now is that my wife is the only person that the cat will allow to touch her. She will get angry, growl, hiss and puff up when anyone else approaches her, or is even in the house. She will tolerate me and used to let me pet her and play with her, but now if I even look at her she gets "pissy". Here tail starts flapping wildly and she starts to growl. My wife feels that she is more tolerant of women, but I have not observed this myself.
I am not sure what happened to her, or why she got this way. Any advice would be greatly appreciated.
