Why
Xylitol is found in sugar-free gum, candy, baked goods and some toothpaste. The ASPCA says it can cause low blood sugar and possibly liver damage, with signs that can progress to seizures.
What to do instead
- Keep gum, mints and sugar-free products sealed away.
- Use only pet toothpaste on your cat.
Warning signs
- Call a vet or poison line right away.
If your cat ate xylitol
- Note how much your cat ate and when, and keep any packaging.
- Call your vet, an emergency clinic, ASPCA Animal Poison Control ((888) 426-4435) or the Pet Poison Helpline (855-764-7661).
- Don't make your cat vomit unless a vet tells you to.
Other sweets: quick answers

Rules for any new food
- Plain is the rule: no salt, butter, oil, onion, garlic, sugar or sweeteners. Most of the danger in human food comes from what is added to it.
- Keep all treats under 10% of your cat's daily calories . The rest should come from a complete cat food.
- Check labels for onion and garlic powder, which turn up in stock, gravy, baby food and seasoned meat.
- If your cat has a health condition, such as diabetes, kidney disease or a sensitive stomach, ask your vet before adding any new food.
