Can guinea pigs eat lettuce, and why?
Avoid iceberg lettuce for guinea pigs; pick darker leaves. Iceberg lettuce is watery, low in nutrition and can cause digestive upset; romaine and leafy varieties are better.
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.
