Can guinea pigs eat butternut squash, and why?
Only a small piece of butternut squash occasionally for guinea pigs. Starchy and sugary; offer sparingly.
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
Starchy and sugary; offer sparingly.
