Can guinea pigs eat xylitol, and why?
Keep xylitol away from guinea pigs. Artificial sweeteners are harmful and should never be fed.
Guinea pigs are herbivores who need unlimited hay or grass, a daily portion of fresh leafy veg, and a daily source of vitamin C — which they cannot make themselves. Their gut relies on constant fibre, so too much sugar or any sudden change can cause painful bloat and diarrhoea.

Artificial sweeteners are harmful and should never be fed.
