A certain stud’s offspring do indeed have the reputation for being nutty and aggressive. Problem is, he was a damn fine looking cat, who sired a loooooooot of kittens, and the aggression passed down pretty reliably.

AAM had some of his descendants and can tell you more.

It's all breeding, whether it's cats or dogs or horses. You gotta watch the pedigree. Cats are more hard-wired and less dependent on proper socialization than dogs, so what you see is what you get, mostly.

There was a particular Quad Gr Ch who was hell on wheels, I saw him bite right through a judge's hand at a cat show and flee under the bleachers (there's some sort of rule that a cat show has to be in a school gym) and bite everybody who tried to winkle him out (including his owner).

I had one of his descendants, I saw him in the pedigree and thought "Uh-oh," but he was 4 generations back and the kitten's mother was a sweet affectionate soul, so I thought it would be o.k. . . . mostly it was, but every now and then he would chomp on somebody. But he was the only Siamese I ever had (and I had a bunch - bred and showed them for years before I got into dogs) who had a tendency to bite people. They would all bite mice, rats, crickets, etc. and any dog that looked at them funny, but not people.
