What happens when you take kittens away from their mother?
The Ideal Age to Adopt a Kitten
Ideally, kittens should go to their new home around 12 weeks of age. While some kittens can go home earlier, the closer you wait until 12 or 13 weeks, the better off the kitten will be. Your cat's chances of being healthy, well-socialized, and properly developed are dramatically increased by allowing it to spend extra time with its mother and littermates.
