- If possible, provide the packaging or recipe of the product ingested to your veterinarian to aid in identification of the toxin.

EFFECTS OF TOXICITY
Chocolate contains stimulants and diuretics that can effect cardiac and central nervous issues. Toxicity depends on the type and amount of chocolate ingested. Only 4 small squares of cooking chocolate is enough to kill a 5 kilogram cat.
Veterinary care may be intensive and include activated charcoal or gastric lavage, intravenous fluids, medication to control seizures and cardiovascular support.
