Guinea pigs are herbivorous creatures and should receive a varied diet of fruits, vegetables, leafy greens, water and food pellets to stay healthy and free from obesity or any health concerns. Ensuring they receive enough variety is crucial.
Spinach is an excellent source of vitamin C, calcium and iron but its high levels of oxalates may bind with minerals like Calcium leading to bladder stone formation. We advise feeding spinach only sparingly.

Vitamin C
Guinea pigs cannot produce vitamin C due to a genetic mutation and thus require it in their diet for multiple uses, including wound healing, bone formation and blood clotting. Furthermore, vitamin C plays an integral part in fighting off scurvy which is potentially lethal.
As with other green vegetables, spinach is an excellent source of Vitamin C; however, guinea pigs should only consume small quantities as it may cause bloating and indigestion in these animals. Furthermore, spinach contains high concentrations of oxalates which bind with calcium absorption receptors in their digestive systems – this could lead to kidney or bladder stones formation in these creatures.
To mitigate these risks, guinea pigs should only receive fresh spinach leaves twice weekly (ideally chopped up into smaller pieces for easier administration), or small amounts of kale that has similar health benefits but is lower in oxalates. In either case, be sure to wash and chop carefully prior to feeding any veggies to guinea pigs.
Calcium
Guinea pigs are herbivores and therefore require plenty of indigestible fibre to keep their digestive systems moving efficiently. This comes from feeding Timothy or Orchard hay as well as fresh leafy greens such as parsley, romaine lettuce, cilantro and dandelion leaves for example.
Calcium is an essential nutrient for guinea pigs as it helps them maintain strong teeth and bones. Their bodies use homeostasis to ensure the calcium reaches all areas of their bodies where needed – so when feeding their calcium they do so carefully.
As part of their daily diet, guinea pigs need access to plenty of timothy hay for calcium intake as well as high-fiber timothy pellets such as Burgess Excel. Furthermore, providing your pet with fresh vegetables like kale, collard greens, turnip greens and Brussels sprouts is ideal as these foods contain low calcium levels as well as celery leaves, watercress chicory escarole radish carrot greens are other nutritious choices!
Magnesium
Guinea pigs require magnesium to alleviate body aches and maintain strong heart muscles. Magnesium also plays an essential role in maintaining stable blood sugar levels, managing stress and anxiety levels, as well as preventing diabetes and cardiovascular diseases.
Guinea pigs require potassium for optimal blood pressure and heart function, healthy skin and hair growth, support of normal immune system functions, as well as cell and tissue development.
While spinach contains essential vitamins and minerals for guinea pigs, its high levels of oxalates may lead to urinary problems in small animals. Therefore, feeding them spinach only occasionally is best. Instead, their body can access these essential nutrients more readily through feeding timothy, orchard, or oat hay that contains lower oxalate levels; additionally this satiates their natural desire for chewing to promote dental health.
Iron
Guinea pigs need iron in their diets to avoid anemia and promote bone growth, digest food better, improve skin health and help reproductive abilities and immunity systems.
Spinach is an excellent source of both vitamins C and iron, but care must be taken in its preparation as its stems and stalks may pose choking hazards to guineas pigs. Furthermore, overfeeding may result in weight gain as well as health problems for them.
spinach contains oxalates (calcium binders), which may lead to bladder stones in guineas. Bladder stones can be painful and require surgery and medicine for your pet to recover; if this has happened to your guinea pig before, avoid spinach altogether and opt for other leafy greens with low levels of oxalates like parsley or kale instead; you could even provide safe fruits rich in vitamin C to satisfy their vitamin needs.
