- Guinea pigs have teeth that are always growing, both the front teeth (incisors) and the back teeth (molars). If their teeth don’t wear down normally (either as a result of poor diet or unfortunate genetics), a guinea pig’s tongue can become trapped and she cannot eat.
- Guinea pigs should not live on a wire floor. They need a solid surface and soft bedding (for example fleece, towels, or a layer of recycled paper litter). Otherwise they can get bad foot sores.
- Guinea pigs need additional vitamin C in their diet, just like people. The best sources are from foods high in vitamin C (like bell peppers), but some commercial treats for piggies are available. Avoid adding vitamins to their water, as this can grow molds or bacteria.
- Never allow a female guinea pig older than 5-6 months to become pregnant for the first time. She is likely to die in labor due to fusing of the pelvis. Keep males and females separated or get your males neutered!
Common medical issues of guinea pigs include: dental disease, ovarian cysts (females), foot sores, bite wounds (from other guinea pigs) and urinary sludge or bladder stones.
