Can cats eat caffeine?
No, cats should not drink coffee, tea, or energy drinks, and coffee grounds can be enough to matter. Caffeine can cause hyperactivity, vomiting, a fast heart rate, or tremors. Call a veterinarian or a poison hotline the same hour.
Portion and preparation
None. A spilled energy drink or coffee grounds can be enough; 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
Caffeine is a methylxanthine, like theobromine in chocolate, and dogs and cats clear it slowly. Coffee, tea, energy drinks, grounds, and pills all count, and a spoon of grounds can matter more than a sip of milky coffee. Keep the package where pets cannot reach it.
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.
- Hyperactivity
- Vomiting
- Fast heart rate
- Tremors
What if this was eaten?
Call a veterinarian or poison hotline the same hour. Keep the cat confined and bring the product label; do not offer milk as an antidote; bring the package and the pet's weight in pounds (kilograms) when you call. Do not induce vomiting unless a veterinarian or poison specialist tells you to.
Which agencies regulate this advice?
The FDA regulates pet food and animal drugs in the United States. The VMD licenses veterinary medicines in the United Kingdom, where DEFRA also sets animal-health rules, and the APVMA registers veterinary chemical products in Australia.
