Can guinea pigs eat cranberry, and why?
A tiny amount of fresh cranberry occasionally for guinea pigs. Acidic and sugary; only a small piece now and then.
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
Acidic and sugary; only a small piece now and then.
