I think your Harmanie will be just fine after her spaying. Our Briggs had her surgery four and a half years ago and she is a wonderful, crazy, loving (when she's interested) , normal cat!!! She's full of cattitude which was not removed along with her reproductive organs. I would say it's a myth that cats' personalities are altered for the worse by spaying or neutering. On the contrary, it relieves them of the hormonal crazies that can affect them if they DON'T have the procedures. Don't worry. She really will be OK. Honest!!!!
