Can guinea pigs eat cinnamon, and why?
Guinea pigs should not be given cinnamon. Spices are unsuitable and can irritate the gut.
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.
Warning — what to watch for
Spices are unsuitable and can irritate the gut.
