Can guinea pigs eat caffeine, and why?
Caffeine is toxic to guinea pigs. 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.
