Humans LOVE chocolate! But did you know that chocolate in all forms in poisonous to cats and dogs?
Chocolate and cocoa contain caffeine and theobromine which are both toxic to dogs and cats.
Theobromine and caffeine cause an increased heart rate. A pet that consumes toxic amounts of chocolate will experience nausea, vomiting, diarrhea, and restlessness.
Dark chocolate contains more of the stimulants than milk chocolate, and unsweetened chocolate and baking chocolate contains even higher amounts, which make them more dangerous. White chocolate contains only trace amounts of caffeine and theobromine, but is still bad for your cat or dog and should still be avoided.
