Can cats eat xylitol gum?

Q: Can cats eat xylitol gum?

Deadly for dogs; a cat study found little effect. Still no reason to give it. In dogs xylitol triggers an insulin surge with low blood sugar and liver failure. In a 2018 study, cats given up to 1,000 mg/kg didn't develop low blood sugar, so cats appear far less sensitive. Gum is still a choking hazard and sugar-free products contain other additives — and in a home with a dog it's dangerous to keep around at all.

Don't.
