The ancestor of the house cat is the African wild cat.
Its kittens can be tamed and they make good mousers. From there, the cat became part of our lives.
Yes, but there is a theory that Housecat DNA also comes from other places on the planet. The Caspian Sea area, for instance, and another place, and these synthesized into the modern housecat.
I note that the Turkish Van cat is the only breed that actively seeks out and enjoys playing in water. Wassup wit' dat?
