I've always been a lurker here, but I just had to reply to this one! I've had two Siamese cats as well and they are really something else, aren't they? My first Siamese cat was actually put on kitty Valium. This was around 1990, so I'm not sure if this is still done or what not, but you can always check with your vet. My cat had fallen high off a shelf which then crashed on him and broke his leg... he had to wear a cast for 6 weeks! At any rate, the Valium seemed to calm him down alot. The Siamese I have now was just as bad... luckily when I added another kitty into the house, it helped tremendously. My Russian Blue is bigger, faster and heavier than my Siamese, so she's calmed down considerably... she's probably afraid she's going to get her little cat butt kicked, lol. I know that's not an option for everyone, though. It sounds like your cat is still a kitten or young (she still has baby teeth?) so there's always the possibility she'll grow out of her spazziness... at least a little. Good luck, sounds like there's never a dull moment!
