I have a very aggressive cat. She's territorial of me and frequently shows aggressive behaviour towards my husband, occasionally bites me if she doesn't get her way, and becomes a wild stalker (hissing, spitting, growling and a couple of time literally attacking people) whenever we have company. (Yes, we put her in a closed room when people come over.) We've previously tried Prozac, which zoned her out but had no effect on her aggressive behaviour, and now we're consulting with a behaviouralist who's recommending amitryptine(sp?) and therapy. Does anyone have experience working with this particular antidepressant with cats? We really love Tiki and will do anything to try to help her--but if this doesn't work, we'll have to find a no kill farm for her, but I just can't bear the thought of giving her away. This situation is becoming unbearable and my husband has three small scratches on his cheek and about ten scratches on his hands....please, any advice is appreciated.
