No. Chocolate is toxic to cats. It contains theobromine and caffeine, which cats metabolize very slowly, and the darker the chocolate, the smaller the dangerous amount. Baking chocolate and cocoa powder are the most concentrated. Treat any ingestion as a poisoning event.

Why this answer
Cacao contains methylxanthines — mainly theobromine plus caffeine. Cats clear these compounds far more slowly than people, so they build up and overstimulate the heart and nervous system. Dark and baking chocolate can hold ten times the theobromine of milk chocolate, so even a lick of melted baking chocolate matters at a cat's body weight.
Watch for
Vomiting or diarrhea, often within 2–4 hours
Restlessness, pacing, or trembling
Fast or irregular heartbeat
Rapid breathing or panting
Muscle tremors or seizures in serious cases
How much is okay
None. There is no safe serving of chocolate, cocoa, or chocolate-flavored desserts for cats.
Keep it away
Store chocolate bars, baking chocolate, and cocoa powder in closed cabinets, not on counters.
Keep cats out of the kitchen while you melt or bake with chocolate.
Watch holiday setups — advent calendars, gift boxes, and dessert trays are common exposure points.

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.
