Can Cats Eat Chocolate? I Updated Toxicity & Safety Guide
Understand why even a little bit of chocolate can be deadly for your cat – and what to do if it does. Cats should never eat chocolate. Chocolate actually consists of theobromine and caffeine, which are toxins to cats because they aren’t good at metabolizing when compared with humans. And even a small bite can lead to vomiting, tremors, seizures, heart failure or death. If your cat eats chocolate, call your vet straight away, or a pet poison hotline. The Reason Chocolate and Cats Are a Bad Idea Chocolate toxicity is more prevalent in dogs, but cats are even more sensitive to the dangerous ingredients. Chocolate toxicity occurs when a cat ingests cocoa-based products such as baking chocolate, cocoa powder, dark chocolate or milk chocolate. Unlike humans, cats do not possess the liver enzymes necessary to metabolize theobromine and caffeine. They build up in their system, causing the heart and central nervous systems to become over-stimulated, which is why chocolate is off limits for cats due to its toxicity.

Baking and dark chocolates contain the most theobromine (400 to 1,200 mg/oz), so two-tenths of an ounce (≈6 g) is sufficient to make an average 8 lb (3.6 kg) cat sick.
