Can cats eat chocolate?
No, cats should not eat chocolate in any form, even if they rarely seek it out. A small amount still contains theobromine and caffeine. Call a poison hotline the same hour, and do not wait for dramatic signs.
Portion and preparation
None. Cats rarely seek chocolate, but a small amount is still a poison exposure; there is no safe home portion in ounces (grams), and a smaller pet can be harmed by less than a larger one. Powder, broth, and baked goods count the same as the plain ingredient.
Why this matters chemically
Theobromine and caffeine are methylxanthines that dogs, cats, birds, and small pets clear slowly. Baking chocolate and cocoa powder contain more theobromine per ounce (per gram) than milk chocolate, so a small missing piece is more dangerous in a small animal.
What clinical signs can appear?
Signs vary with the amount eaten, the animal's weight in pounds (kilograms), and how much time has passed. The list below is what clinics commonly ask about. It is not a checklist that rules disease in or out for one animal.
- Vomiting
- Hyperactivity
- Fast heart rate
- Tremors
What if this was eaten?
Call a poison hotline the same hour. Cats hide illness, so do not wait for dramatic signs. Keep the cat indoors and away from the rest of the chocolate; do not induce vomiting at home; note the product and the time.
Which agencies regulate this advice?
The FDA regulates pet food and animal drugs in the United States.
