Thanks for the responses. I went through some of the past threads and I think I'm not going to go the Clomicalm route. The Calm Spirit Tea pills sound like a good alternative. Do these come from a holistic vet or from the health food store? I'm not sure if we have this in Canada but I'll look into it. Paddy is so sweet and neat and interesting, I would hate myself if I gave him something that might take any of that away. I'm wondering using a multiple product approach would work. I could keep the Feliway plugged in and keep giving Rescue Remedy and try to find the Calm Spirit pills. (I should probably make sure I can give both the calm spirit pills and rescue remedy at the same time). At the very least, it should help with the new aggression towards our female cat. He sets his sights on her and his pupils get huge and then she starts growling at him and then he chases her and he then sits under wherever she has climbed to safety and he 'waits'. As soon as I noticed this going on (started yesterday) I separated them for a time. Not sure what is going on there.
Does anyone give rescue remedy mixed in wet food? I know alot of people put it in water but I have multiple water bowls around and he and the other cats drink from all of them.
