I have a lovely pure-bred siamese. Most well-behaved cat I've ever had. When her time comes, I'll definitely get another. They're known for their good temperament.
And volume! My mother had a Tonkinese (Siamese/Burmese mix), and that little thing had the biggest voice you ever heard. Lived to be 22--we kept anticipating her "last Christmas," she ended up having about eight of them--and was the queen bee to the end. My sister had a Russian Blue, incredibly loving cat, but terribly jealous. Used to pee on me while I slept to mark his territory (me), so the other cats (sis had about a dozen) wouldn't claim possession of me.
I'm down to two myself, and I swear one's retarded, but the sweetest little thing you could imagine. Deaf as a post any more, and about as bright. The other's a DSH that thinks she's a Siamese with the noise she makes, and insists on crawling under the covers with me.
Face it. They're all weird.
