What Milk Can My Cat Drink?

So many cartoons depict cats drinking milk, but in reality, milk isn't healthy for cats! Here's why milk isn't great for your cat and what you can give them instead.

While we often picture cats happily lapping up a bowl of milk, the truth is, most cats shouldn’t drink milk!

At Applaws, we want to help cat owners make the best choices for their pets. So, what kind of milk (if any) is safe for cats? Here’s what you need to know.

Can Cats Drink Regular Cow’s Milk?

No, most cats are lactose intolerant. While kittens can digest milk from their mothers, adult cats lack the enzyme lactase, which helps break down lactose in dairy products. This can lead to:

  • Upset stomach (vomiting or diarrhea)
  • Bloating & gas
  • Discomfort & dehydration

Tip: Even if your cat seems to tolerate cow’s milk, it has no nutritional benefits for them and is best avoided.

What Milk Is Safe for Cats?

If you want to treat your cat to some milk, choose cat-friendly alternatives:

  • Specially formulated cat milk – Lactose-free and enriched with nutrients.
  • Goat’s milk (in small amounts) – Lower in lactose but still not necessary.

Tip: Kittens under 8 weeks old should only drink their mother’s milk or a kitten-specific milk replacer, not cow’s milk.

The Best Drink for Cats? Fresh Water!

The healthiest and safest drink for cats is plain, fresh water. Make sure your cat has:

  • A clean water bowl refreshed daily
  • Multiple water sources around the home
  • A cat water fountain if they prefer running water

Tip: If your cat isn’t drinking enough water, try Applaws wet food to keep them hydrated.
