Why this answer
Donuts combine fried fat, refined flour, and sugar glaze, a heavy load for a small carnivore that can trigger vomiting or pancreatitis-type upset, and offers zero nutrition. Chocolate icing brings theobromine, and any sugar-free or 'skinny' glaze could contain xylitol, so toppings can turn a junk food into a hazard.
Watch for
Vomiting or diarrhea from the fat and sugar
Stomach pain or reduced appetite
With chocolate glaze: restlessness or rapid heartbeat
How much is okay
None is needed; a nibble of plain donut is unlikely to poison a cat, but the fat and sugar mean donuts should stay off a cat's menu.
Serve it safely
Keep donut boxes closed and off counters cats can reach.
Do not offer glazed or chocolate donuts to a cat at all.
Clear plates and greasy wrappers promptly.

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.
