According to the ASPCA, it is best to leave your kitten with its mother for at least 4 weeks. This will ensure that your kitten receives all the antibodies she needs from her mother’s milk. The healthiest kittens are those who have been nursing on their mothers for at least 12 weeks. However, some breeders allow kittens as young as 8-weeks of age to be weaned if they are being raised in a group situation where other siblings are still nursing (like foster homes). If you choose this option, make sure you pay very close attention to any signs of illness or disease; these problems may progress quickly and could cause severe damage before you can get them under control!
