I'm sorry, THE forget YOU SAY ABOUT LIVES?
Chocolate is poisonous in high dosages, I've known this for what, 4 years :D
Theobromine is especially toxic to horses, dogs, parrots, voles, and cats because they are unable to metabolize the chemical effectively. If they are fed chocolate, the theobromine will remain in their bloodstream for up to 20 hours. Medical treatment involves inducing vomiting within two hours of ingestion and contacting a veterinarian.
