Quick Reference: Not recommended — most adult cats are lactose intolerant
✅ Safe to eat
- • Cat-specific milk (lactose-free formula)
- • Small amounts of goat's milk (lower lactose content)
⚠️ Use caution
- • Kittens gradually lose the ability to digest lactose after weaning
- • Even cats without obvious symptoms don't need milk as part of their diet
✗ Not safe
- • Regular whole cow's milk
- • Flavored sweetened milk drinks
- • Butter and ice cream
Why Can't Most Cats Handle Cow's Milk?
It's one of the most enduring myths in pet care: cats love milk. In reality, according to Cornell University's College of Veterinary Medicine, most adult cats are lactose intolerant.
Kittens can digest their mother's milk just fine, but as they grow, their bodies produce less and less lactase — the enzyme needed to break down lactose. When an adult cat drinks regular cow's milk, the undigested lactose ferments in the gut and causes:
- Diarrhea
- Bloating and gas
- Abdominal discomfort
Safer Alternatives
If you'd like to give your cat a milk-like treat:
- Cat milk: Available at most pet stores, these products have had the lactose removed
- A little goat's milk: Lower in lactose than cow's milk, but still best in small amounts
- Fresh water is best: Ultimately, clean water is all your cat really needs for hydration
