Can guinea pigs eat coffee, and why?

Coffee is toxic to guinea pigs. Caffeine can cause dangerous heart and nervous system effects.

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

Caffeine can cause dangerous heart and nervous system effects.

If your guinea pig has eaten coffee, 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.
