Mints have an array of benefits apart from their amazing taste and smell. The following are some of the best-known benefits of the mint plant:


Aids in Digestion

Mint has some characteristics that are known to help deal with stomach upsets and disorders. In most cases, digestive problems appear by food staying too long in the stomach without going through the rest of the digestive system. Mint improves the digestion, thus reducing the chances of gastrointestinal complications in the guinea pig’s body.

Some of the compounds found in certain types of mint have shown the ability to boost the performance of some brain functions. The brain controls most, if not all of the processes in the body, and having a healthy brain equals a healthy life for your little pet.


Aids in Weight Loss and Control

Dietary fiber found in mint can induce satiety and when your guinea pig eats the mint it will reduce the food intake, which in the long run, reduces the overall number of calories taken into the body. When calories are reduced, the whole process will lead to the loss of weight and control as well.


Prevents Constipation

Mint has dietary fiber which is known for its ability to boost bowel movements. Sometimes your guinea pig may have problems passing the stool and giving it foods rich in fiber such as mint can be of great help.


Mint Improves Eye Health

Due to the presence of vitamin A in the plant, it can improve eyesight and macular health. The vitamin A helps eliminate any infections that may affect the guinea pig’s eye.


The Plant Boosts Immunity

In case your guinea pig’s immune system is weak, you can give it mint as well. This is due to vitamin A, apart from boosting eyesight, it also helps to improve the immunity of your pet.

Risks to Consider When Feeding Mint to Guinea Pigs

Risks to Consider When Feeding Mint to Guinea Pigs

Apart from the fact that some mints lack vitamin C, there are also a few risks that may face your guinea pig if you feed it with this veggie. In summary, take a look at the following possible risks:


Lack of Vitamin C

As we can see in the table above, spearmint lacks an essential nutrient needed by guinea pigs. Vitamin C is vital for guinea pig’s life because they can neither create nor store this vitamin on their own. Denying your guinea pig food that contains this vitamin is equivalent to shortening their lifespan. This is because they need this vitamin to survive.

On the other side, peppermint is loaded with vitamin C and other nutrients that benefit your guinea pig. This is wrong to say that spearmints have zero nutritional content, but the fact that they have little to no vitamin C makes it useless for guinea pigs. So, if you want to give your guinea pigs mint, it’s better to choose peppermint than spearmint.


Allergy

Some types of mint may have allergic effects on your guinea pig. In case you offer your guinea pig a mint and later notice that it has some allergic reactions, it is best to stop giving them this herb. In case the situation gets out of hand, you need to get advice from a qualified vet.


Digestion Problems

Mint leaves can contain pests or chemicals on it, which can cause serious problems to your guinea pig. That is why it is wise to wash the plant thoroughly before feeding it to your cavy. Washing will remove any pests or chemicals that may be residing on the plant.

Also, if you feed too much mint to your guinea pigs, it will lead to stomach problems. If you notice symptoms such as diarrhea, vomiting, or gases, stop feeding too much mint to them and regulate their diet.


Urinary Problems

The amounts of calcium and sodium in mint are quite big, which can be a problem for guinea pigs. If your guinea pigs consume foods rich in calcium and sodium, they may develop urinary problems. Sodium, but especially calcium, can cause the development of bladder or kidney stones in guinea pigs. This is why you need to be careful with the serving sizes of mint and provide them foods that are low in calcium.
