Xylitol is toxic to cats, though the mechanism differs from dogs. Cats do not experience the same dramatic insulin release that dogs do, but xylitol still causes liver toxicity and gastrointestinal distress. Any ingestion warrants a vet call.
Why Is This Toxic to Cats?
While the hypoglycemia seen in dogs is less prominent in cats, xylitol can cause hepatic damage and severe GI symptoms. Research in cats is more limited than in dogs, making the full toxic picture uncertain.
Xylitol is found in hundreds of products — sugar-free gum, some peanut butters, toothpaste, mouthwash, vitamins, and medications. Always check labels before letting your cat explore.
| Product | Xylitol Content | Risk to Cats | Action |
|---|---|---|---|
| Sugar-free gum | 0.3–0.4g/piece | Any amount — call vet | Emergency |
| Peanut butter (some) | Varies | Any amount | Emergency |
| Toothpaste/mouthwash | High | Any licking | Call vet |
| Sugar-free candy | Variable | Any amount | Call vet |
