Can dogs eat xylitol (sugar-free sweetener)? And cats?
Extremely toxic. Found in sugar-free gum, candy, and some peanut butters.
Toxicity in cats is not well established, but avoid it: there is no upside.
Xylitol triggers a massive insulin release in dogs, crashing their blood sugar within 30 to 60 minutes, and larger doses can cause liver failure. It hides in sugar-free gum, mints, candy, toothpaste, and some peanut butters, so always check labels before sharing peanut butter. Even one or two pieces of gum can be an emergency for a small dog.
