Can cats drink milk?

Last updated: 2026-10-12

Short answer: Most adult cats can't digest the lactose in milk well, and milk and dairy can cause diarrhea and an upset stomach. Fresh water is what a cat should drink. Orphaned newborn kittens need kitten milk replacer, not cow's milk; ask a vet.

Lactose and digestion

According to the ASPCA, pets don't have significant amounts of lactase, the enzyme that breaks down milk sugar, so milk and dairy can lead to diarrhea and other digestive upset.

What should a cat drink?

Clean, fresh water, always. Some cats prefer running water, and placing the water bowl a little away from the food bowl can help. Follow your vet's advice on the type and amount of cat food.
