Can Kittens Drink Milk?
-
Newborn Kittens Need Milk—But Not Cow’s Milk
- Fact: Newborn kittens rely on their mother’s milk or a kitten milk replacer (KMR) to grow and thrive.
- Why Not Cow’s Milk?: Cow’s milk contains lactose, which many kittens cannot digest properly, leading to stomach upset, diarrhea, and dehydration.
-
Weaned Kittens Don’t Require Milk
- Fact: Once kittens are weaned (around 8 weeks old), they no longer need milk as a source of nutrition. Their dietary needs can be met with high-quality kitten food.

Common Myths About Kittens and Milk
-
Myth: All Cats and Kittens Love Milk
While some cats enjoy the taste of milk, this doesn’t mean it’s good for them. In fact, most adult cats and many kittens are lactose intolerant, making milk a poor dietary choice. -
Myth: Milk Is a Complete Meal for Kittens
Milk lacks the essential nutrients kittens need to grow, such as high-quality protein, taurine, and certain vitamins. Relying on milk alone can lead to malnutrition. -
Myth: Milk Can Replace Water
Milk is not a substitute for water. Staying hydrated is critical for your kitten’s health, especially if they eat dry food. Learn about hydration strategies in our post, “The Importance of Hydration: Wet vs. Dry Cat Food.”.

Safe Milk Alternatives for Kittens
If your kitten is unable to nurse or you need to supplement their diet, consider these safe options:
- Kitten Milk Replacer (KMR): Specially formulated to mimic the nutrient profile of a mother cat’s milk, KMR is the best alternative for orphaned or nursing kittens.
- Goat’s Milk: In limited amounts, goat’s milk can be easier for kittens to digest compared to cow’s milk. However, it should never replace a balanced diet.

Contact your veterinarian if symptoms persist, as dehydration can be dangerous for kittens.
