Dark chocolate is strictly forbidden for cats. The available data shows no nutritional value or health benefits for felines.
Risks and scientific explanations
Dark chocolate contains concentrated theobromine, which leads to severe chemical toxicity. The danger applies to all types of chocolate, but the darker it is, the more toxic it becomes. The toxic parts include cocoa beans, cocoa powder, and dark chocolate itself, and they remain dangerous in any state.
The toxicity is caused by methylxanthines, which have a central and cardiac stimulant effect. Cats experience a slow clearance of these substances, which can cause serious cardiac and neurological disorders, and possible death. Cats with low body weight are especially vulnerable as the toxic threshold is reached quickly.
Poisoning symptoms to monitor
Symptoms of poisoning can appear between 2 and 24 hours after ingestion. You should carefully monitor for the following signs:
- Vomiting
- Diarrhea
- Hyperactivity
- Tremors
- Convulsions
What to do in case of ingestion
A lethal dose can be around 80 to 200 mg per kg of body weight. If your cat ingests dark chocolate or if any concerning symptoms appear, you must contact a veterinarian immediately.
