Cocoa

Cocoa is the main ingredient used to make chocolate and is produced from processed cacao beans. It is not safe for cats because it contains high levels of the methylxanthines theobromine and caffeine. Cocoa powder is especially dangerous because these compounds are much more concentrated than in most finished chocolate products. The main risk comes from theobromine and caffeine. Cats break down these substances much more slowly than humans, so even relatively small amounts can build up in their bodies. These compounds overstimulate the nervous system and cardiovascular system, causing prolonged stimulation that can affect heart function, blood pressure, and normal neurological activity. If a cat eats cocoa, signs may include restlessness, unusual hyperactivity, drooling, vomiting, diarrhea, a rapid heart rate, fast breathing, and muscle tremors. In severe cases, seizures, abnormal heart rhythms, or life-threatening complications can occur. Because cocoa powder is far more concentrated than most chocolate products, even a small amount should be taken seriously. Keep all cocoa-containing products, including cocoa powder, baking cocoa, and high-cocoa chocolate, out of your cat’s reach. If you suspect your cat has ingested any cocoa product, contact a veterinarian as soon as possible.

Important Notes

Symptoms: Vomiting, diarrhea, excessive thirst and urination; rapidly progressing to agitation, rapid heart rate, tremors, hyperthermia, cardiac arrhythmia, and seizures.

Most toxic common source: Cocoa powder is more dangerous per gram than dark chocolate, baker's chocolate, or any other chocolate product — treat any exposure as a serious emergency.

Hidden sources: Hot cocoa powder, chocolate baking mixes, and cocoa mulch (used in gardens) all contain high methylxanthine levels.

Action: Veterinary emergency. Even a small amount of cocoa powder requires immediate veterinary attention.
