Can guinea pigs eat walnuts, and why?
Walnuts are not suitable for guinea pigs. Far too high in fat for a herbivore’s 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.
