Is Mint Bad for Guinea Pigs? | Possible Risks

Risks to Consider When Feeding Mint to Guinea Pigs

There are also a few risks that may face your guinea pig. 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.


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 them, 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 and 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 with foods that are low in calcium.
