Up to what age do cats feed their kittens with milk? - in detail
Cats typically nurse their kittens with milk for about eight weeks, which is roughly half of a cat's gestation period. During this time, the kitten's primary source of nourishment and immunity comes from its mother's milk. The first few days after birth are crucial as the kitten receives colostrum, a form of milk rich in antibodies that helps build the kitten’s immune system. As the kittens grow, their mother's milk production increases to meet their nutritional needs. By the time they reach eight weeks, kittens should be fully weaned and transitioned to solid food, although some mothers may continue to nurse for a bit longer depending on individual circumstances.
