Indigenous animals are not well-suited to be domesticated and assist in farming.
The cats … they're domesticated and really very nice.
The principal domesticated animal is the yak.
The ordinary domesticated cats of Europe are, however, mainly of African origin, although they have largely crossed, especially in Germany (and probably also in Great Britain), with the wild cat.
In view of these differences from the domesticated breed, and the resemblance of the skull or lower jaw to that of the extinct European species, it becomes practically impossible to regard the wild camels as the offspring of animals that have escaped from captivity.
