How to Use Cat Chocolate Toxicity Calculator

The Cat Chocolate Toxicity Calculator helps you translate chocolate type and weight into a theobromine dose.

  1. Enter cat weight — Use kg or lb.
  2. Identify the chocolate type — Baking and dark chocolate carry the most theobromine per gram.
  3. Estimate amount eaten — Round up when uncertain.
  4. Note time since ingestion — Vomiting decontamination is most effective within the first 2 hours.

Formula & Theory — Cat Chocolate Toxicity Calculator

Toxicity depends on theobromine load:

theobromine_mg = amount_g × mg_per_g[type]
dose_mg_per_kg = theobromine_mg ÷ weight_kg
# white 0.1, milk 2, dark 6, semi 8, baking 16

The Cat Chocolate Toxicity Calculator is a quick reference, not a substitute for veterinary advice. Always cross-check with a vet, especially for medication or toxicity questions.

Frequently asked questions about Cat Chocolate Toxicity Calculator

Are cats less sensitive than dogs?

No — cats are similarly sensitive but rarely eat chocolate by choice. When they do, smaller body size means even small amounts matter.

What about cocoa mulch?

Garden cocoa mulch is dangerous for any pet. Use cedar or pine mulch instead.

How long do symptoms last?

Theobromine has a long half-life in pets (up to 18 hours). Watch for at least 24 hours after a moderate ingestion.

First aid before the vet?

Keep your cat calm and cool. Do not induce vomiting at home — it must be done by a veterinarian.
