Xylitol is not considered highly toxic to cats in the same way it is to dogs, but it is not safe. Ingestion can cause gastrointestinal upset, including vomiting and diarrhea. While it does not typically trigger the severe insulin spike seen in dogs, any amount should be avoided.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Unlike dogs, cats do not have the specific insulin response to xylitol that leads to hypoglycemia. However, xylitol is a sugar alcohol that cats cannot digest efficiently, leading to osmotic diarrhea and potential stomach irritation. There is no established lethal dose for cats, but individual sensitivity varies.
🩺 What to do
- Monitor your cat for signs of vomiting, diarrhea, or lethargy for 24 hours after ingestion.
- Prevent access to xylitol-containing products like gum, candy, or baked goods.
- Contact your veterinarian if symptoms persist or if a large quantity was consumed.
❓ Common questions
Is xylitol as dangerous for cats as it is for dogs?
No, cats are generally less sensitive to xylitol's effects on blood sugar, but it still causes digestive issues.
What happens if my cat eats a piece of xylitol gum?
They may experience vomiting or diarrhea, and the gum itself could pose a minor choking or blockage risk.
Can I use xylitol toothpaste for my cat?
No, you should use a pet-specific enzymatic toothpaste, as xylitol is unnecessary and potentially irritating for felines.

| Source | Dogs | Cats | Dose info |
|---|---|---|---|
| ASPCA Animal Poison Control | Listed as toxic — xylitol can cause low blood sugar (hypoglycemia) and potentially liver damage depending on amount ingested; initial signs vomiting, lethargy and loss of coordination, progressing to seizures; liver damage can occur within 12-24 hours (page written for pets generally, no species split) | Listed for pets generally — same xylitol section with no cat-specific distinction or separate cat warning on this page | — |
| Pet Poison Helpline | Toxic to dogs — causes a dangerous, rapid drop in blood sugar and can also cause liver failure; any amount should be treated as a potential danger, even small amounts can potentially cause a dangerous drop in blood sugar | Not toxic in the same way — page states xylitol does not appear to cause the dangerous drop in blood sugar in cats that it causes in dogs; still advises contacting a vet/helpline because other ingredients in sugar-free products can harm cats | — |
| Merck Veterinary Manual | Toxic to dogs — xylitol toxicosis occurs in dogs; rapid dose-dependent insulin release can result in profound hypoglycemia, and some dogs develop severe hepatic insufficiency or failure | Not at risk — page states explicitly: 'Dogs are the only domestic species in which xylitol toxicosis has been reported; cats are not at risk for hypoglycemia or liver injury from xylitol toxicosis' | Dogs: >~100 mg/kg (45 mg/lb) associated with hypoglycemia; >500 mg/kg (227 mg/lb) may develop severe hepatic insufficiency or failure |
| VCA Hospitals | Extremely toxic to dogs — even small amounts can cause hypoglycemia, seizures, liver failure, or even death; lower doses cause hypoglycemia, higher doses cause liver failure | Not covered | — |
