Plain water-cooked oats are safe in small portions. Avoid flavored packets, sweetened toppings, and rich oat desserts. Too much fiber and carbohydrate can loosen stool.
Oats are whole cereal grains sold as groats, steel-cut, rolled, and quick oats for porridge, baking, and snack bars, providing carbohydrates and soluble fiber.
Breakfast products often add sugar, milk, butter, syrups, and dried fruit. Granola and instant cups can be far richer than plain oats.
Oat-based cookies and bars add fats and sweeteners that change pet suitability. Plain oats also appear in some commercial pet formulations.
