Oatmeal: Safe for Dogs and Cats?

Plain oatmeal cooked in water, not milk, is safe for dogs in moderation and can offer fiber and skin-supporting nutrients, but flavored oatmeal and large portions can cause digestive upset.

Safe serving: A small amount of plain oatmeal cooked in water, offered once or twice a week.

Oatmeal is not toxic to cats but is not a natural or necessary part of an obligate carnivore's diet, so most vets advise against feeding it regularly and recommend only small, plain amounts if any.
