I've had 4 of my cats on Clomicalm for inappropriate spraying. I've never had an issue w/it, no side effects of any kind. I just recently discontinued giving it to one of my cats b/c she was taking meds for an ear infection and a bad eye and it was becoming increasingly difficult to catch her. LOL She went off it cold turkey and there were zero side effects. I do know what you mean about having to be weaned off it b/c I was taking one myself for fibromyalgia and I wasn't weaned off it. She side effects were horrible. However, I don't think you need to worry about it w/your cat but, if it will make you feel better, then gradually cut the dosage down until she's off it.

I didn't want to give them drugs either but after so much spraying b/c pee wars were started by just one cat, it was a real necessity. Clomicalm and kitty prozac aren't the same thing but they are both for aggression and inappropriate spraying, also for separation anxiety. One of my cats was a bully but he's been on Clomicalm for years now and he's really mellowed. I give them 5 mg. at bed time and it doesn't drug them at all, just keeps them peaceful. Believe me, Yodie (the one on whom I just discontinued Clomicalm) races around the house as though she were on fire and this is when she is ON Clomicalm. If you feel that your cat is rather drugged from it, try playing w/the dosage a bit. It may take some time until you get it just right. Also, my vet said that it takes 8-12 weeks before it starts to work but it worked immediately for my cats.

I hope this helped a little and if you have any questions, please feel free to PM me. I'll be happy to help in any way that I can.
