Oxalates are toxic and can cause kidney problems.

Why

Never feed rhubarb to guinea pigs.

Can guinea pigs eat rhubarb, and why?

Never feed rhubarb to guinea pigs. Oxalates are toxic and can cause kidney problems.

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

Oxalates are toxic and can cause kidney problems.

If your guinea pig has eaten rhubarb, 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.
