Gum
Chewing gum is potentially toxic to cats depending on its ingredients. Sugar-free gum and many mints contain xylitol — an artificial sweetener that is highly toxic to cats and dogs. Xylitol triggers a massive release of insulin from the pancreas, causing dangerous hypoglycaemia, and at higher doses causes liver failure. Regular sugary gum is not chemically toxic but poses a physical hazard.
Important Notes
Toxic compounds: xylitol (in sugar-free gum, some mints, and dental products) — check ingredient labels
Mechanism: xylitol stimulates insulin secretion independent of blood glucose levels, causing severe hypoglycaemia; hepatotoxic at higher doses
Symptoms: vomiting, weakness, incoordination (ataxia), tremors, seizures (from low blood sugar); liver failure may follow 24–72 hours later
Regular sugar-based gum: choking hazard and GI obstruction risk from swallowed gum mass; not chemically toxic
Keep all gum, breath mints, and xylitol-containing products sealed and stored away from cats; any suspected xylitol ingestion is an emergency
Possible Symptoms Reported in Cats
Hypoglycemia and Liver Failure (Theoretical / Rare)
Neurological · 15 to 30 minutes for a drop in blood sugar (though it can be delayed up to 12 hours for products lik
Unlike dogs, who suffer severe and life-threatening reactions to chewing gum containing the artificial sweetener xylitol
Metabolic
Gastrointestinal Upset
Gastrointestinal · Within a few hours.
Transient Salivation (Drooling)
Gastrointestinal · Shortly after ingestion.
