Can cats drink milk? Yes, cats can drink milk, but it’s not recommended as many cats are lactose intolerant and can’t properly digest lactose, a natural sugar found in milk. This can lead to digestive issues such as an upset stomach, vomiting and diarrhea.
Kittens are the only ones who should drink milk, and that should only be their mother’s milk until they are weaned.
If you want to give your adult cats a treat, it’s better to offer them water, wet food, or even a little bit of plain yogurt or cheese that is low in lactose.
