Can guinea pigs eat blackcurrant, and why?
A tiny amount of fresh blackcurrant occasionally as a vitamin-C treat. Quite acidic and sugary, which can upset digestion; never give dried currants.
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
Quite acidic and sugary, which can upset digestion; never give dried currants.
If your guinea pig has eaten blackcurrant, 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.
