Serving advice
Treat oatmeal as a snack rather than part of the daily ration — the usual ceiling is about 10% of daily calories. Start with one small piece of oatmeal and watch stools and appetite over the next 24 hours.
Plain cooked oatmeal without added sugar, salt, or butter is safe for dogs and cats. It provides soluble fiber and can soothe an upset stomach. Ensure it is fully cooked and cool before serving; watch for any signs of intolerance.
Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.
There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter
A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
