Is milk bad for cats?
Unless they are spoiled or moldy, milk, cheese and other dairy foods are not considered to be poisonous to pets. However, cats do not possess significant amounts of lactase, the enzyme that breaks down lactose in milk. Feeding milk and milk-based products to cats can actually cause them to vomit or have diarrhea, which in severe cases could lead to inflammation of the pancreas. For this reason, it’s always a good idea to check with your veterinarian before offering any “people food” to your pets.
