The Siamese Cat Song...

Many black cats are part Siamese...  A mating of practically any color cat with a Siamese cat often produces black kittens.  If you see a black cat with a triangular face, a lean, svelte body with long back legs and a long tail who has a loud, deep voice that cat very possibly has Siamese blood.

Lestat definitely was part Siamese.  He had a very triangular face, a strident meow and went around corners like a locomotive, his front end going north while his hind quarters was still heading east.  :D
