Is there anything I can do to stop my 12 y.o. female from "freaking out" every time she sees my 2 y.o. male? (both are fixed). We have had him for 4 months but she still throws a hissing and growling fit every time she sees him and hides. When they are on opposite sides of a door, she will either bat and claw at the door or put her paws under it, hissing and growling. He doesn't hiss at all but he will jump on her when he gets the chance, which freaks her out even more, so basically we keep them separated. There is a kitten as well that they both get along with. Unfortunately this is very stressful for all involved, including myself! His scent is all over the place but it's the sight of him that makes her freak out. We tried to introduce them slowly at first, but we had no success in calming her down so we have just kept them separate. I hope it's not too late as we don't want to get rid of him. I have tried Feliway and Rescue Remedy on both of them but nothing helped. She will eat on the other side of the door from him with it partly open, but if he looks up at her she freaks and runs away. She will also eat with him in a crate nearby but if he's out she freaks.
