Can guinea pigs eat breakfast cereal, and why?
Guinea pigs should not eat breakfast cereal. Sugar and starch are harmful to herbivores.
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
Sugar and starch are harmful to herbivores.
