same with russian fox fur breeders. i don't remember the numbers, but after a surprisingly small number of generations the foxes turned into cat-like pets.
It wasn't for fur, they ran a long-term selective breeding experiment just to see if they can pull it off.
Tails curled, ears drooped and they became mostly white.
Yes, that's a quite famous experiment, and still ongoing. Similar effects of "domestication syndrome" have recently been reported in wild urban foxes and raccoons.
