The Cat Chocolate Toxicity Calculator assesses risk when your cat eats chocolate. Cats are actually more sensitive to theobromine (the toxic compound in chocolate) than dogs, though they rarely eat it due to lacking sweet taste receptors.
Every result is based on published veterinary research and veterinarian-reviewed formulas — not generic averages. Completely free, works instantly, requires no account or sign-up.

Frequently Asked Questions
Yes. Cats process theobromine more slowly than dogs, making them more vulnerable to toxicity at lower doses relative to body weight.
Cats lack the taste receptors for sweetness, so chocolate is far less appealing to them than to dogs — but accidental ingestion still happens.
Call your vet or emergency animal poison line immediately, regardless of the calculated risk level. Cats can react unpredictably.
Vomiting, diarrhea, restlessness, rapid breathing, increased heart rate, tremors, and in severe cases, seizures.
