Do guinea pigs like bananas?

So, guinea pigs CAN eat bananas, but do they LIKE them? 

As with all animals, taste preferences differ. However, it’s safe to say that most guinea pigs are banana fans, with the sweetness of these yellow snacks appealing to a guinea pig’s taste buds, however there certainly are drawbacks to bananas. This is why you should be sure to regulate the amount of banana that your guinea pig is eating – left to their own devices, they’d happily snack away!

How much banana can I feed my guinea pig?

A couple of cubes of banana is an ideal serving for your guinea pig. This treat should be limited to 2-3 times a week and should not be offered for two days in a row. 

The bananas should be ripe and fresh. It is important to let your guinea pig smell the banana before giving it to them. If they don’t like it and leave it sitting in their cage, the banana will eventually become harmful to eat.

Do bananas have health benefits for guinea pigs?

The short answer is, in small amounts, yes! Bananas include:

  • Antioxidants: can help protect cells from damage from free radicals
  • Vitamins A, B1, B6 and C: they contribute to protecting the guinea pig’s immune system, as well as looking after their growth, reproductive system and eyesight
  • Essential minerals including potassium, magnesium, calcium and iron: strengthen bones and tissues

The benefits of vitamin C for guinea pigs

Vitamin C deficiency in guinea pigs can lead to scurvy, poor skin and bone health and weight loss. 

Guinea pigs cannot produce their own vitamin C and so it is crucial that it is supplemented within their diet. While bananas do provide vitamin C, they shouldn’t be relied upon as the main source of the vitamin. Vitamin C supplements can easily be picked up in pet stores.

Are bananas bad for guinea pigs?

In small doses, bananas are a perfectly safe treat for your guinea pig. 

However, the question of whether guinea pigs can eat bananas is a bit more complicated, given the nutritional makeup of bananas.

Bananas are made up of 12% sugar, making them one of the most sugary fruits going. For context, this is twice the amount of sugar that is in a strawberry.

Feeding too much banana to your guinea pig can lead to gas, bloating, upset stomachs and diarrhea. These nasty side effects can result in dehydration, meaning a trip to the vet might be necessary.

Because bananas are so high in sugar, your guinea pig overeating them can not only lead to diarrhea but even risk diabetes. Just like humans, guinea pigs can get both Type 1 and Type 2 diabetes from a high-sugar diet or from being overweight.

Can bananas kill guinea pigs?

Bananas are not poisonous to guinea pigs, however the high volume of sugar can lead to obesity which is not good for your little pet’s health.

Can guinea pigs eat banana peel?

Banana peel is a funny issue! While it is perfectly safe for your guinea pig to eat, the chewy peel is often less appealing than the soft, tasty fruit inside. So don’t be surprised if your pet chomps on the banana flesh but ignores the peel.

However…

The peel itself is actually quite nutritious for your guinea pig. It contains:

  • Antioxidants (fight danger molecules called free radicals which can lead to cancer and heart conditions)
  • Fiber
  • Potassium (helps muscle movement)
  • Magnesium (benefits metabolism)
  • Vitamins B6 and B12 
  • Protein

If possible, buy organic bananas if you want to feed the peel to your guinea pigs in order to avoid any dangerous pesticides that might have been sprayed by banana farmers. However, even with organic fruit, it is still important to wash the skin before giving it to your guinea pig, just to stay on the safe side.

So feel free to feed your guinea pig a little bit of banana peel, but prepare for them to reject it. You’ll even have the added bonus of using up some of the skin, rather than just having to throw it away!

Can guinea pigs eat dried bananas?

Any sort of dried banana (including banana chips) should be avoided. They tend to be highly processed and coated in sugar, in addition to the high level of sugar already existing in the banana.

Artificial oils and flavourings can also be added to dried banana chips which would be harmful for your pet. So, if you’re going to feed banana to your guinea pig, be sure to stick to the fresh fruit.

Alternatives to banana

While we’ve learned that bananas are safe for guinea pigs to eat, it might be worthwhile looking for snack options that aren’t so loaded with sugar. Some tasty fruit alternatives include:

  • Blueberries
  • Strawberries
  • Grapes
  • Melon (especially watermelon!)
  • Pineapples

Meanwhile, some delicious and healthy vegetable options are:

  • Asparagus 
  • Cucumbers (including the skin)
  • Squash
  • Zucchini
  • Carrots (including the tops)
  • Broccoli (but in moderation as too much can cause gas)
  • Pumpkin
  • Celery (but try to remove the strings which can be a choking hazard)
  • Peppers (of any color – very high in vitamin C)
  • Parsnip

Are there other foods to avoid feeding your guinea pig?

Before feeding your guinea pig, it really is important to investigate which foods might harm your pet. There are several ways in which foods can be dangerous: they might be poisonous, lead to gas or bloating, be very high in fat or sugar, have no nutritional value or be choking hazards. A list of the key foods to avoid feeding your guinea pig includes:

  • Chocolate (or anything else containing caffeine)
  • Onions
  • Garlic
  • Mushrooms
  • Iceberg lettuce
  • Avocados
  • Nuts
  • Potatoes
  • Seeds
  • Corn kernels
  • Peanut butter

Let’s talk about bananas

Let’s chat a bit about the bananas themselves.

Bananas are native to Asia but are now enjoyed globally as a tasty snack. They need warmer climates to grow and so can usually be found in tropical climates. 

Distinctive for their bright yellow skin, bananas can actually be many different colors ranging from green to red. 

Bananas contain many healthy properties, including fiber, potassium, vitamin B6, vitamin C, phytonutrients and antioxidants. 

Technically, bananas are part of the berry family and grow on plants that can be up to 25 feet high. A bunch of bananas is called a hand while one single banana is called a finger. Between 10-20 banana fingers can be found on one hand! 

With over 100 billion bananas eaten each year globally, they are recognized as being the fourth most popular agricultural product in the world.
