Theobromine Toxicity Symptoms & Dose Threshold Table
| Theobromine Dose (mg/kg) | Toxicity Level | Expected Clinical Symptoms & Emergency Action |
|---|---|---|
| < 20 mg/kg | Low / Minimal Risk | Mild stomach upset possible. Rest and monitor at home. |
| 20 – 40 mg/kg | Moderate Toxicity | Vomiting, diarrhea, restlessness, hypetivity, increased thirst. |
| 40 – 60 mg/kg | Severe Toxicity | Tachycardia (ing heart rate), cardiac arrhythmias, severe agitation. Vet visit required. |
| > 60 mg/kg | CRITICAL LETHAL POISONING | Muscle tremors, seizures, coma, cardiac failure. Immediate emergency vet hospitalization needed! |
Calculation Methodology & Biological Principles
Theobromine Dose Formula
Methylxanthines inhibit adenosine receptors and phosphodiesterase, elevating intellular cyclic AMP and overstimulating feline cardiac muscle cells.
Veterinary Disclaimer
Do not induce vomiting in cats at home using hydrogen peroxide, as it causes severe hemorrhagic gastritis. Decontamination must be done by a vet.
Frequently Asked Questions
Why is chocolate toxic to cats? ▼
Chocolate contains methylxanthines (specifically theobromine and caffeine). Cats metabolize these compounds much more slowly than humans, leading to dangerous central nervous system stimulation, elevated heart rate, and cardiac arrhythmias.
Do cats like chocolate? ▼
Cats lack sweet taste receptors, so they rarely crave sweet foods. However, cats may accidentally ingest chocolate if mixed with milk, butter, or ice cream.
Which chocolate type is most dangerous for cats? ▼
Baking chocolate and cocoa powder are extremely hazardous because they contain high concentrations of theobromine (up to 26 mg per gram), whereas milk chocolate contains much less (approx 2 mg/g).
