Oatmeal is fairly high in protein and fats, containing linoleic acid and amino acids that are good for healthy skin and coat.
Risks
Feeding oatmeal too often or as the main part of their diet can cause digestive issues and an imbalanced diet.
Cats' digestive systems are primarily designed to digest meat, and foods high in carbohydrates should be avoided.
Suggestions
Oatmeal should only be given as an occasional treat.
It can be added in small amounts to their wet food, cooked plain in water, or offered as oat tea.
Ensure that commercial cat food remains the major part of your cat's diet.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
