Q: Is Gum toxic to cats?

Caution: potentially harmful. Chewing gum is not chemically toxic to cats, but a swallowed piece can still cause problems. The main risk is mechanical: a wad of gum cannot be digested and may cause choking or a gastrointestinal blockage, especially in a small cat. Many people worry about xylitol, the sweetener in sugar-free gum. Xylitol is genuinely dangerous to dogs, but authorities including the ASPCA state that cats are not negatively affected by it. A 2018 study gave cats doses up to 1,000 mg/kg with no drop in blood sugar, no liver damage, and only brief drooling. So the chemical poisoning seen in dogs does not apply to cats. There is still no reason to let a cat eat gum. If a cat swallows gum, watch for drooling, vomiting, reduced appetite, or signs of an obstruction such as repeated retching or straining, and contact a veterinarian if these appear. Keep gum out of reach to avoid the choking and blockage risk.

Mostly fine, with one catch.

Symptoms reported in cats

Most serious first.

1
Gastrointestinal Upset or Obstruction Within a few hours. · The indigestible gum base cannot be broken down and can act as a foreign body, potentially causing a physical gastrointestinal obstruction. Watch for vomiting, repeated retching, straining, or reduced appetite.
2
Transient Salivation (Drooling) Shortly after ingestion. · In a 2018 experimental study where cats were given oral doses of xylitol up to 1,000 mg/kg, the cats exhibited no changes in blood glucose, liver enzymes, or hematological parameters. The animals remained well, with transient salivation being the only reported clinical sign.

Main hazard is mechanical, not chemical: a swallowed gum wad is indigestible and can cause choking or a gastrointestinal blockage, especially in a small cat
Xylitol is NOT toxic to cats: the ASPCA states people, cats, and ferrets are not negatively affected by xylitol, and a 2018 study found no hypoglycaemia or liver damage in cats at doses up to 1,000 mg/kg
The severe hypoglycaemia and liver failure caused by xylitol are a dog-specific risk and do not apply to cats
Signs to watch for after a cat swallows gum: brief drooling, vomiting, reduced appetite, or signs of obstruction such as repeated retching, straining, or lethargy
Keep gum and breath mints out of reach to prevent choking and blockage; contact a veterinarian if obstruction signs appear
