Can cats eat chocolate?
No — and if your cat has already eaten chocolate, call a vet or poison control now rather than waiting for symptoms to appear.
Why
Chocolate contains theobromine and caffeine, which pets clear from the body far more slowly than we do. The darker the chocolate, the more theobromine — baking chocolate and cocoa powder are the most dangerous, milk chocolate less so, white chocolate mostly a fat-and-sugar problem.
What to watch for
Vomiting, diarrhea, restlessness, panting, excessive thirst and urination, racing heart, muscle tremors, seizures. Signs often start 6–12 hours after eating.
What to do
Call now, before symptoms appear. Have the wrapper ready — the type of chocolate and your pet's weight decide whether this is serious.
For cats specifically:
Chocolate is toxic to cats just as it is to dogs.
If they've already eaten some, don't wait for symptoms
This page is not veterinary advice and is not a diagnosis. It's a general reference for a common food, and it can't account for your pet's size, age, health conditions, medications, or how much they actually ate. Toxicity is almost always about dose. If your pet has eaten something you're worried about — or is showing any symptoms — call your veterinarian, an emergency animal hospital, or a poison control hotline right away. Never induce vomiting unless a veterinary professional tells you to.
