  • Can Cats Digest Milk? 

Cats' bodies only produce enough lactase, the enzyme responsible for lactose digestion, during their infancy and early years of life when they feed on their mother's milk. 

As they mature, the production of lactase decreases, leading to possible digestive issues if they consume milk. Therefore, it's crucial to be cautious when giving cats milk, as their bodies may struggle to digest lactose which results in complications.

  • Can Kittens Drink Milk? 

Yes, kittens can drink milk, but only their mothers’ milk. During their early life stages, kittens still can digest lactose, while they grow, the ability decreases, so it’s recommended to provide them food diet that meets their needs.

Cats and cow milk generally don't go well together. Most adult cats are lactose intolerant, meaning they lack the enzyme to digest milk sugar (lactose). This can lead to unpleasant digestive issues like diarrhea and vomiting. Cow milk isn't very nutritious, even for cats who tolerate lactose, and can contribute to weight gain. If your cat enjoys milk, lactose-free cat milk alternatives are available as an occasional treat. But remember, water is always the best drink to keep your feline friend healthy and hydrated.
