she is
A beautiful mix of one of the wild cats (Felis silvestris) and our house cat (Felis silvestris lybica). Becoming rather common in the West, also found a lot in parts of Mexico. All cats breeding looks like a horrid fight...
All felids are capable of self-domestication, since no cat is 'broken' to us as are dogs or sheep or such. Although it's not a lie to say she's a domestic cat, it's a bit like the neighbors down the road calling their wolf a malamute because of stupid city laws in Fort Collins. Genetically, a-yup, she's a wolf or a malamute, as you like...all dogs are genetically wolves. The variations among the felids fall into such a narrow range, interbreeding is no problem.
I noticed the tail, too. Mine do that when something intrigues them, when they are uncertain and when they are about to give somebody the thrashing they deserve. She obviously regards the child as a 'kitten', else that tail pulling would not be tolerated.
I'd love one, but I don't know. The only cat my cat ever liked was a Maine coon, she would probably shove Magic down the stairs and break her neck like she did with the American Eskimo which so chased her.
