Can cats eat xylitol?
Do not feed xylitol products to cats, including sugar-free gum and some liquid medicines. Cats do not show the dog insulin spike in published reports, but the sweetener is still not cat food. Call if a cat eats a labeled product.
Portion and preparation
Do not feed xylitol products. Some liquid medicines use it as a sweetener; 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
Xylitol, also labeled birch sugar, can trigger a sharp insulin release in dogs and drop blood sugar within about an hour. Cats do not show that same spike in published reports, but a xylitol sweetener is still not food for any pet.
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.
- Vomiting
- Lethargy
- Wobbliness
What if this was eaten?
Call a veterinarian if a cat eats a xylitol product, especially a large amount or a medicine. Save the label; do not give a second medication to settle the stomach. Bring the package and the pet's weight in pounds (kilograms) when you call.
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.
