Is giving a fifteen week old kitten milk bad for it?

Kittens typically start weaning from their mother's milk around eight weeks old. By fifteen weeks, they are usually completely weaned and drinking water as their primary source of hydration. However, some kittens may still be interested in drinking milk, and it can be a source of vitamins, minerals, and protein. That being said, milk should only be given as a treat, and not as a primary source of nutrition. Additionally, it is important to make sure that the milk is kitten-approved, as some types of milk can cause digestive problems in kittens.
