Why is xylitol bad for cats?
Cats are obligate carnivores: they must get certain nutrients (taurine, arachidonic acid, preformed vitamin A) from animal tissue, so a complete, balanced cat food should always be the base of the diet. The food on this page is the exception that proves the rule: cats' small bodies and unique metabolism make certain human foods genuinely dangerous, not just "unhealthy." If your cat has eaten it, treat it as urgent.
Xylitol (a sweetener in gum, peanut butter, baked goods, toothpaste) can trigger a catastrophic insulin release and liver failure in cats.
"ASPCA warns xylitol causes low blood sugar (hypoglycemia) and potentially liver damage; products marketed “sugar-free” are the usual source." — PetMD
What to do if your cat ate xylitol (4 steps)
- Move it away. Remove the remaining food so no second helping lands.
- Collect the facts. What kind, roughly how much, and when — the wrapper helps.
- Call immediately. Your vet or ASPCA Animal Poison Control (888) 426-4435 — cats hide illness, so do not wait for symptoms.
- Do not induce vomiting unless a professional tells you to.
