How long after birth do kittens wean?

Kittens generally wean at 40 to 45 days; if the mother’s milk is low, wean a few days earlier with pet goat formula. Some mothers overproduce and pups keep nursing; then adjust the mother’s diet to avoid blocked glands. Timely weaning matters because as kittens grow, milk no longer meets needs and long nursing harms the mother’s health.
