Caution

Key risk

Why

Grapefruit is very acidic and best avoided for guinea pigs.

Can guinea pigs eat grapefruit, and why?

Grapefruit is very acidic and best avoided for guinea pigs. The high acidity can cause mouth sores and digestive upset.

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

The high acidity can cause mouth sores and digestive upset.

If your guinea pig has eaten grapefruit, 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.
