Can guinea pigs eat flax seeds, and why?
Only a tiny amount of flax seed occasionally for guinea pigs. High in fat and not a natural food; offer only rarely.
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
High in fat and not a natural food; offer only rarely.
