A few common questions
Can this tell me my cat is safe?
No. Chocolate exposure should be discussed with a veterinarian or poison control, especially when the amount or type is uncertain.
Why does chocolate type matter?
Darker and baking chocolates usually contain more methylxanthines than milk or white chocolate, so smaller amounts can be more concerning.
