Is Chocolate Toxic to Cats?
Yes — chocolate is toxic to cats. It contains theobromine and caffeine, both of which cats cannot metabolize efficiently. While cats are less likely to seek out chocolate than dogs (they can’t taste sweetness), accidental ingestion does happen and can be dangerous. Our cat chocolate toxicity calculator helps you quickly assess the risk level based on your cat’s weight, the type of chocolate, and the amount consumed.
Chocolate Toxicity Levels in Cats
| Chocolate Type | Theobromine (mg/oz) | Risk Level |
|---|---|---|
| White chocolate | ~3 mg | Very low |
| Milk chocolate | ~44 mg | Moderate |
| Dark chocolate | ~150 mg | High |
| Baking chocolate | ~390 mg | Very high |
| Cocoa powder | ~600 mg | Extremely high |
