So I've been wondering for year how my sweetheart Chocwa ended up with crimped/curly hair. It was more pronounced as a kitten but still visible as an adult. He also has extremely brittle whiskers that fall off and break every few months, and his ear hair is course and dry. His parents were both siamese, his father was a snowshoe and his mother a chocolate point, neither having this type of hair.The lady whom I bought him from told me he was the only one in the litter to have this, the rest were normal. What would cause this?
