Can guinea pigs eat hazelnuts, and why?
Hazelnuts should not be given to guinea pigs. Too fatty; they cannot digest nuts.
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.
