Can guinea pigs eat acorns, and why?
Acorns are toxic to guinea pigs and must be avoided. Tannins can cause severe poisoning.
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
Tannins can cause severe poisoning.
