Siamese cats can be mean. I had one once. Don't pick it up, it might yank out one of your eyes.
Well, of course, I won't pick up a random Siamese cat I see in my backyard...that would be like trying to pickup a racoon and not get bitten and scratched. I highly doubt, anyways, I could ever catch it. I see a Siamese cat, a Calico, and a grey/blue cat from time to time cross my window. I'm in love with the Siamese one. I'd love to own two, a pair, when I move into my new home.
