Can guinea pigs eat fizzy drinks, and why?

Guinea pigs must only drink plain water. Sugar and caffeine are harmful to herbivores.

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

Sugar and caffeine are harmful to herbivores.

If your guinea pig has eaten fizzy drinks, 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.
