Is there a different med that you could try? Medusa is a big fan of Clomicalm - it doesn't zone her kitties out.

I also use a "Feliway Collar" - Oscar wears a very stretchy collar, and I shake the bottle of Feliway and put a squirt into it in the morning. Storm might need three squirts a day.

My vet told me the patent has come off Feliway, so it's almost half the price it used to be!

Or - maybe once he is weaned off the Prozac, he will have the habit of being calmer.

Glad he was so good at the vet - what a sucky boy!
