Why this answer
Oats are a whole grain high in soluble fiber, non-toxic to cats and occasionally used to add gentle bulk to stool. Cats gain no essential nutrition from them, though, since they run on animal protein rather than plant carbohydrate. The typical toppings are the danger: raisins can cause kidney injury and chocolate is toxic, so only plain cooked oats are appropriate.
Watch for
Loose stool or gas from the extra fiber
Bloating if the portion is too large
How much is okay
A teaspoon of plain oatmeal cooked in water, offered occasionally rather than as a routine breakfast share.
Serve it safely
Cook plain rolled oats in water until soft and let them cool.
Skip milk, sugar, honey, and any flavored instant packets.
Never add raisins, chocolate, or sweetener toppings.

Feeding Your Cat
Cornell Feline Health Center, Cornell University College of Veterinary Medicine — Feline nutrition fundamentals: cats are obligate carnivores; complete balanced cat food should be the diet base; treats should stay a small share of daily calories.
Petfoodology
Cummings School of Veterinary Medicine at Tufts University — Board-certified veterinary nutritionist guidance on pet diets, treat limits (about 10% of daily calories), human-food snacks, and species-appropriate feeding for cats and dogs.
Raisin and Grape Toxicosis in Dogs
Merck Veterinary Manual — Grape and raisin ingestion associated with acute kidney injury; dose-response is unpredictable, anecdotal reports exist in cats, and conservative management treats any ingestion as potentially serious.
Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
