Can guinea pigs eat green beans?

Most people who pet guinea pigs wonder whether these small animals can eat green beans.

As herbivores, guinea pigs eat fresh vegetables and fruits, but not all are equally beneficial for their health.

Guinea pigs need an unlimited supply of timothy hay and fresh and clean water every day, as well as natural food rich in vitamin C.

To keep your pet healthy, you should know which nutrients they should eat, which foods are dangerous to them, as well as the amount of food they should consume every day.

Can Guinea Pigs Eat Green Beans?

Green beans, otherwise called string beans, are a staple food in numerous dishes around the world.

Guinea pigs need to eat food that is rich in vitamin C, as they can not synthesize this nutrient.

For that reason, there is a variety of manufactured guinea pig foods high in vitamin C.


Can Guinea Pigs Eat Green Beans Every Day?

Yes, guinea pigs can eat green beans.

However, a healthy guinea pig’s diet rests on an equilibrium of hay, guinea pig pellets, and fresh and raw fruits and vegetables.

Just like people, guinea pigs can’t make their own vitamin C, so they require vitamin C-rich nourishments in their everyday diet.

Green beans are plentiful in Vitamin C, fiber, and other fundamental supplements, which are indispensable for every guinea pig.

In any case, green beans are high in oxalic corrosive and calcium, which can prompt illnesses in guinea pigs.

So, since we can give green beans to our guinea pigs, let’s understand the dietary benefits of this vegetable and how acceptable it is for our guinea pigs.

Note that a guinea pig might love green beans, that doesn’t imply that all guinea pigs eat this vegetable with equal delight.

Some guinea pigs may love this food, while others may dislike it.

However, that is expected because guinea pigs are fussy about food.

As already said, a guinea pig’s healthy daily diet consists of large quantities of hay and small quantities of fruits and vegetables.

Feed your guinea pig green with beans 1-3 times per week.

Pay attention to the amount of food that you give to your guinea pig.

Never give your guinea pig more than one to two strings of green beans at a time.

Green beans are a good source of vitamin C, fiber, and other essential nutrients for guinea pigs when served in limited quantities.

An average guinea pig needs around 30mg/kg of vitamin C per day.

Oxalates are found in many plant nourishments.

Nonetheless, the amount of calcium and oxalates together may be troublesome for guinea pigs, if taken in huge quantities.
