Sugar-free gum (xylitol) — Food safety facts
Feed with care · Cats · full breakdown on the linked food page
Xylitol is a true emergency for dogs — hypoglycaemia within 30 min, liver failure possible. Cats are far less sensitive.
Dogs are rated “Do not feed” and cats “Feed with care”. If both share the house, go by the stricter of the two when you decide what to hand over.
Sugar-free gum (xylitol) is not poisonous to cats, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.
If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.
Why these cautions matter
Even a gram or two of xylitol can trigger a sharp drop in a dog's blood sugar, and larger exposures go on to damage the liver.
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
