Ember had Mau Ancestry because they are a rare breed and expensive. Most breeders are careful to avoid accidental matings. If one does happen, they neuter or spay the kittens before giving them away. Most Mau breeders also neuter or spay pedigrees before they sell them in order to prevent amateurs from trying to breed them or from carelessly letting them mate with other cats. That's one reason why they are so rare. I suspect the motive is to keep the price high.
The breeder that Ember's mother came from was known among breeders to be less careful and could not get accreditation as a Bengal breeder because of that. Bengal breeding has to be very well regulated because Bengals are a mix of an Asian wild cat with the domestic Mau to breed the wild behavior out of the Asian cat. Legally, only the 4th generation of the mixture can be sold as a pet, for safety reasons.
The Bengal breeder that Ember's mother came from eventually went out of business because they could not get accredited.
The wiggle tail behavior in Maus often looks like a male cat spraying, but that's not what it is. It not a random act or something that happens only in reaction to one object. It is an expression of great happiness or positive, happy excitement. Ember does it most often when she sees that she is getting food, especially a food that she really loves. But she also does it when she sees that I am going to play with her with one of her favorite toys. It's as if she is thinking, "Oh goody. I just can't wait to get started."
A couple times Ember did it when I returned home after being out for a while, which was flattering to me that my return made her so happy. Maus are not lap cats, but they do not like to be alone, either. They love interactive play with people and tend to bond with one person more than with others. So that's why she was so happy to see me come home.
