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.

Warning — what to watch for

Iceberg lettuce is watery, low in nutrition and can cause digestive upset; romaine and leafy varieties are better.

If your guinea pig has eaten lettuce, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
