Why Should Guinea Pigs Eat Leaves?

There are countless benefits of feeding a guinea pig with leaves.

The most vital ones are:

Eases the Growth of Teeth

Guinea pigs experience pain when their teeth grow. Sadly, their teeth are constantly growing. Thankfully, leaves contain vitamin C, which makes the process tolerable.

In addition, leaves strengthen their teeth so that they’re able to feed on pretty anything you give them.

Prevention of Scurvy

The vitamin C found in leaves protects your guinea pigs from scurvy. The disease highly threatens the life of your pet.


Scurvy causes internal bleeding, which puts the life of your pet at risk. The disease also causes a lack of appetite. The coat of your pigs becomes rough, and their joints swell.

Therefore, feeding your guinea pig with leaves is saving his life and extending it.

Boost Immunity

The nutrients found in leaves, for example, vitamin C, proteins, and minerals, boost the immunity of the guinea pig.

A high immunity helps your pig fight diseases; hence makes him healthy, thereby lowering the chances of falling sick.

Enough Blood

Leaves contain iron. Guinea pigs with enough iron do not suffer from anemia.  Anemia could cause instant death to your pigs.

So, leaves are generally a life-saver.

Safe Delivery

Pregnant female guinea pigs need calcium so that they can have enough for themselves and their young ones.

If not given enough during pregnancy, your guinea pig will have a deficiency in calcium. Consequently, she will have some complications. Some of the signs that prove a female guinea pig is lacking calcium include tremors, dehydration, and muscle spasms.

You may also notice that she looks depressed.

Considering the fact that she is nursing, all the calcium may be drained from her body, and death will come knocking thereafter.

So, ensure that your guinea pig has enough calcium before and after she gets expectant and when she is nursing.

Risks Associated With Guinea Pigs Feeding On Leaves

While there are many benefits associated with leaves, there are risks too.

Stomach Upset

A guinea pig may not stop eating leaves even when he has had enough, especially if he gets his favorite ones. As such, he may eat too much.

In return, he gets a stomach upset.

You can always prevent this by giving enough for the day.

Urinary Health Issues

Too many leaves could also cause urinary sludge and urinary stones, also known as uroliths.

Here’s what happens.

When you over-feed your guinea pigs with calcium, some of it is stored in the urinary tract.

When the guinea pig urinates, only part of the calcium is excreted.  The excess calcium, commonly known as dense calcium crystals, remains at the bottom of the pig’s bladder.

Urine, on the other hand, is stored at the top of the sludge (dense calcium crystals). Uroliths, on the other hand, cause great inflammation in the pig.

They build up between the pig’s kidney and urethra. Uroliths may also cause a urinary blockage as they’re stone-like, hence painful to pass.

In return, your pig may have urinary health challenges, which may cause pain when passing urine.

Bloating and Diarrhea

Diarrhea mostly occurs when you introduce a certain leaf to your pigs. Or, when they take the leaves in large amounts.

Too much diarrhea may cause dehydration, which may eventually claim the life of your guinea pig if immediate and proper action is not taken.

Leaves are treats that you give guinea pigs. Therefore, they’re not an everyday meal. As such, they may get excited and hastily eat the leaves.

When they do, they also swallow air, which is hard to expel. So, their stomachs bloat. They feel uncomfortable when their tummies bloat. It’s, therefore, a good idea to be watchful.

So, for a guinea pig that is still in his growth stage, 1 to 2 leaves per meal are enough.

How Often Should I Feed my Guinea pig with leaves?

Can Guinea Pigs Eat Vegetable Leaves?
