Cat experts! What breed of cat do I have?

You have a possible Siamese mix. Unlike many other cat breeds, unregistered Siamese and Persians are very common. They are sold in pet stores, in ads in the paper, and from 'the lady up the street'. These kittens are sold into irresponsible homes who don't bother with spay/neuter. Then the siamese mom gets out, mates with the cat next door, and the resulting kittens are often lynx pointed. The degree to which these mixed kittens inherit the Siamese personality varies greatly - some of the mixiest ones have more Siamese personality than some of the pedigreed cats do, and others are much more laid back and quiet, inheriting the domestic short hair personality. He is definitely not a pure Siamese, but no matter - he is a very handsome cat indeed.
