Can mice eat chocolate?
Quick Answer
No
Chocolate is toxic to mice. It contains theobromine and caffeine, which can cause serious health problems in mice, including heart problems, restlessness, and in severe cases, death.

Why It Can Be Risky
Feeding chocolate to mice poses several risks:
- Theobromine poisoning: Theobromine, a compound found in chocolate, is toxic to mice. It can cause heart problems, seizures, and in severe cases, death.
- Caffeine toxicity: Chocolate also contains caffeine, which can cause restlessness and rapid breathing in mice.
- Obesity: Chocolate is high in sugar and fat, which can lead to obesity and related health problems in mice.
Safe Alternatives
Instead of chocolate, consider feeding your mice fresh fruits and vegetables, whole grains, and specially formulated rodent pellets.
