What happens if a cat drinks milk?

Most adult cats may experience diarrhea, bloating, and vomiting within 8-12 hours of drinking milk due to lactose intolerance. Small amounts may not cause serious problems, but regular or large quantities of milk are not recommended.

Is there any milk that is safe for cats?

Commercial cat-specific milk has had lactose removed or broken down and is the safest option. Small amounts of lactose-free milk or plain unsweetened yogurt can also be offered occasionally.
