Can guinea pigs eat fish fingers, and why?
Fish fingers are not safe for guinea pigs. A strict herbivore cannot eat fish or a fried, salty coating.
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
A strict herbivore cannot eat fish or a fried, salty coating.
If your guinea pig has eaten fish fingers, 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.
