Guinea pigs need healthy foods and this includes fruits and vegetables.

Bananas are healthy treats that provide guinea pigs with potassium, fiber, vitamins, and minerals. Bananas also have a high sugar content.

Botanically called a berry, a banana is an edible, long fruit of various types of flowering plants of the Musa genus. Bananas are popular for their sweet taste and use in cooking and desserts.

These fruits are natives of the tropical Australian and Indomalayan regions, and Papua New Guinea was probably the first country to domesticate bananas. Currently, bananas are grown across 135 countries. Leading producers in 2017 were India, followed by China.

Guinea pigs are active and socialize well. This pocket pet has a habit of constantly chewing on things due to their ever-growing teeth. With proper diet and care, guinea pigs can live up to eight or nine years old.

Their diet must be made up of low-sugar and low-fat foods. Bananas can be a good treat for your pet.

These furry little creatures are also picky when it comes to food. So, it is necessary to build a routine with your baby guinea pig with a slow introduction of other foods.

This allows them to take in food at their own pace. They won't be able to digest processed or cooked vegetables and fruits. Guinea pigs' digestive systems are more sensitive than those of dogs or cats.

Molars of guinea pigs are best suited to grind plant matter. Fresh green hay like timothy hay makes up almost their entire diet along with food pellets.

Another good choice of hay is alfalfa hay; however, many vets and pet owners state that alfalfa may cause bladder stones and obesity due to excess calcium. Few studies identify alfalfa as food that is a good source of amino acids, fiber, and protein. A guinea pig's diet can also include treats in moderation.

Some illnesses and complications in guinea pigs due to a poor diet are difficulties with pregnancy, teeth problems, vitamin deficiencies, metastatic calcification, and muscular dystrophy.

Dried bananas have way more sugar than raw bananas. Guinea pigs will love these sweet treats but it is best to keep dried bananas away from them. Feeding them dried bananas can cause diabetes.

Banana chips have preservatives and a coat of honey. Guinea pigs cannot eat banana chips in excess.

Guinea pigs also cannot eat banana chips that are prepared with spices in oil. There are, however, banana chips available specifically for guinea pigs. When it comes to juice, store-bought is not an option for guinea pigs.

Guinea pigs cannot eat huge amounts of banana peels. Peels of bananas contain health benefits that are different from the flesh, so the flesh and peel of this fruit are not interchangeable.

These leaves are a great addition to a guinea pig's diet. High antioxidants in leaves are great for a guinea pig's health. These leaves can be mixed in with their veggies and other fruit two to three times a week.

Bananas contain nutrients like vitamin B6, potassium, copper, magnesium, vitamin C, protein, fiber, and manganese. The starch present in unripe bananas gradually converts into sugar as bananas ripen.

How do you feed bananas to guinea pigs?

You can feed bananas to guinea pigs by cleaning and peeling the banana and cutting the fresh banana into slices.

Introducing bananas, like any other fruit, must be done by close monitoring. You can first treat your pet with a banana when he has already eaten and this way he will not feel the need to eat more than necessary.

Guinea pigs love fresh fruits and vegetables. You can give small, fresh banana pieces and observe your guinea pig after around 15 minutes for any kind of reaction.

Provide your pet with the right amounts of calcium and protein every day. You can increase the serving size a little more when guinea pigs are comfortable with this food.

Banana peels should be introduced to your guinea pig like any other fruit treat. Make sure to observe your pet when it starts to eat bananas.

Signs like bloating or diarrhea can indicate a serious health issue. You can make tiny cuts on the banana peels so guinea pigs can hold on to them more easily.

It is also easier for guinea pigs to eat mashed bananas. When you start to feed bananas to guinea pigs, they should be fed bananas not more than two times a week and you can gradually increase it to three times a week.

Bananas need to be ripe and not green as green ones contain too much starch and are bad for guinea pigs. If you are offering your guinea pigs bananas and their peels then make sure to wash them under clean water to get rid of all pesticides and chemicals.

It is also better if you can feed them organic or homegrown bananas and peels.

You can even add in banana leaves. First shred them into small pieces because the hard texture might make it difficult for guinea pigs to swallow them.

Risks To Consider While Feeding

Risks of eating too much banana are diabetes and obesity because bananas are high in sugar, kidney problems, bloating, gas, stomach upset, and diarrhea.

Guinea pigs should not be fed either green or overripe bananas. Overripe bananas have too much sugar and green ones have too much starch.

It is also not good to feed them too much banana, banana peel, or banana leaf. As a guinea pig's digestive system is sensitive, excess bananas are dangerous for its health.

It is advised that you should feed guinea pigs only small amounts of any treat because too much fruit can lead to diarrhea or loose stools. If this happens, make sure to keep your guinea pig hydrated. Ripe bananas contain a lot of sugar.

Too much sugar isn't good for guinea pigs, which is why you cannot feed a whole banana to guinea pigs. When overconsumed this sweet fruit can cause obesity and diabetes.

Like humans, guinea pigs are also susceptible to Type I and Type II diabetes. Kidney stones are formed in guinea pigs due to high calcium.

Moderate amounts of calcium are necessary for the proper development of teeth and bones. Calcium also helps pregnant guinea pigs to take care of their young ones.

High calcium causes either kidney or bladder stones in guinea pigs and is accompanied by blood in the urine. The fiber in bananas aids digestion but if overfed can cause spasms, stomach pain, loose stools, and constipation.

The soluble fiber aids in the slow digestion of food in guinea pigs. This can harm gastrointestinal health. Too much banana can have a negative impact on your pet's dental health.

If your guinea pigs consume too much banana then it can cause hyperkalemia. This is caused by too much consumption of potassium and high electrolytes.

This can increase blood levels, which in turn can cause organ swelling and faster beating of the heart and can be fatal. The hard texture of banana leaves can also be difficult for guinea pigs to swallow and if fed excessively it can cause health issues.

Some advise that owners should only feed bananas to their pets once or twice a month. Some alternative choices for bananas are grapes, strawberries, blueberries, asparagus, melons, pumpkin, zucchini, cilantro, pineapples, butternut squash, and watermelons.
