Can guinea pigs eat corn on the cob, and why?
Only the fresh husk and silks for guinea pigs, not the cob or kernels. The starchy kernels and cob are unsuitable; the green husk leaves and silks can be offered in small amounts.
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
The starchy kernels and cob are unsuitable; the green husk leaves and silks can be offered in small amounts.
