Can Cats Eat Chocolate?

Updated 18 October 2026 · Researched against PDSA, Cats Protection and International Cat Care guidance

Theobromine and caffeine are both present in chocolate, and cats clear them far more slowly than people do. The darker the chocolate, the higher the concentration: cocoa powder, cooking chocolate and dark chocolate are markedly more dangerous than milk chocolate, with white chocolate the least (but still not safe).

Cats are small, so the amount that matters is small too. Signs usually start within a few hours and range from vomiting and restlessness to a racing heart, tremors and seizures. This is one of the few foods where a phone call immediately after the event is genuinely the right move, even if the cat seems fine.

What to watch for in the UK

• Advent calendars, selection boxes and Easter eggs are the seasonal spike — a cat can reach a bag left on the floor in seconds.
• Cocoa powder and baking chocolate are the most concentrated forms and the most dangerous.
• Chocolate-covered raisins combine two toxins: theobromine and grapes.
• Keep chocolate in a closed cupboard, not a handbag or a coat pocket.

If your cat has already eaten it

1. Phone your vet straight away and tell them the type of chocolate, roughly how much, and your cat's weight.
2. Take the wrapper or a photo of the packaging with you — the cocoa percentage matters.
3. Do not wait for symptoms before calling, and do not try to make your cat sick unless a vet tells you to.

Out of hours, use your practice's emergency number. If you can, take the packaging with you — the ingredient list often tells the vet more than the description does. This page explains risk; it cannot diagnose your cat, and it deliberately contains no doses or home treatments.

If your cat is already vomiting, see the cat vomiting guide and vomiting blood. For the wider red-flag checklist, use sick cat symptoms. If a plant rather than a food is involved, the toxic plants checklist is the right page.
