Can guinea pigs eat raw fish, and why?
Raw fish is not suitable for guinea pigs. Herbivores cannot digest fish.
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
Herbivores cannot digest fish.
