Can cats eat chocolate?
No. Chocolate is toxic to cats. It contains theobromine and caffeine, which cats handle poorly, and the darker and more bitter the chocolate, the more dangerous it is. If your cat eats any, call your vet straight away.

Why
Chocolate contains theobromine and caffeine. Cats process these substances differently from people, which makes them more sensitive to their effects. Because cats struggle to break down theobromine, it stays in the blood and can quickly build up to dangerous levels. Dark and bitter chocolate carries the most risk; white chocolate has the least theobromine.
Signs to watch for
- Vomiting
- Diarrhoea
- Increased thirst
- Panting or restlessness
- Peeing more than usual
- Racing heart
- In severe cases: muscle tremors or seizures
What to do
Contact your vet or a pet poison helpline right away, even if your cat seems fine. Note what kind of chocolate your cat ate, how much and when, and keep the wrapper. Don't wait for signs to appear, and don't try to make your cat sick at home.
