I think that's about average.

Most people can distinguish a Siamese, by their points. But then all pointed cats get lumped in there too, like Himalayans, Ragdolls, Tonkies, even long haired cats with points.

On the contrary, many people think they have a Siamese or Siamese mix, and the cat doesn't even have blue eyes.
Most likely they have a cat with an Oriental gene in them.

I'm surprised that people can distinguish ANY cat breed whatsoever.
