Temperament, like size, is massively polygenic--hundreds or thousands of different genes affecting it slightly.pic.twitter.com/UBRazdtFIS

Chickens are sexually mature at, what- 8 weeks? Since 1957 there's been 3-400 generations. Not exactly a short time for selection.

Cursory web search suggests six months or a bit less for chickens. Cats about the same, actually.

Cats do have a much longer reproductive lifespan and aren't under nearly as much selective pressure.

If people ate kitty mcnuggets, we might see cats bred to be muscle-bound. For disturbing trends in poultry, look at turkeys.

The issue is that we're spaying and neutering the friendly, adoptable cats, making the feral population wilder.
