I would talk to your vet about Prozac for your kitty as well - a lot of people here have had a lot of luck with putting their kitty on Prozac. Makes it easier to live with the kitty, and seems to make the kitty happier and more calm.
If your vet is suggesting putting your kitty down rather than trying meds like Prozac, then you need to find a better vet!
