Can guinea pigs eat lime, and why?
Lime is too acidic and harmful for guinea pigs. The intense acidity can irritate the mouth and 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.
