Can Pet Rats Eat Bananas? Benefits & Risks

There’s no secret that rats are highly adaptable and versatile. You will never see a rat starve unless in extreme conditions, such as separated from any potential source of food. These amazing rodents will eat anything they can get and will waste nothing.

Today, we will discuss rats and fruits, more specifically, the relationship between rats and bananas. Do they like them, how much are they allowed to eat, and are there any side effects to banana consumption?

To start things off in full force, yes, rats love bananas just as much as we do. But let’s get into more details.

Are Bananas Good for Pet Rats?

Yes, bananas are good for rats. However, moderation is key, as with anything. Bananas contain a lot of vitamins and minerals, but they are also rich in sugars. Too many bananas will eventually make rats prone to health problems, including obesity and diabetes. Pet rats are more predisposed to obesity than wild ones due to the circumstances.

The pet rats’ diet depends on the owner’s selection of foods. It’s not the rat who decides the meal for the day, but you, the owner. Wild rats don’t have this problem, as they function as scavengers and opportunistic eaters. They will eat anything they can find, making their diet more diverse.

They also cannot gorge themselves as pet rats due because food isn’t as readily available and in such high amounts. Wild rats are also more active overall, given that they’re free to move where they please. This makes them less prone to getting overweight or obese.

For these reasons, you need to avoid giving your rats too many fruits too often. This includes bananas, despite their healthy nutrient content.

Benefits of Bananas for Pet Rats

Bananas are highly nutritious, so they bring a lot of value into your rat’s meal plan. Some notable benefits to consider include:

  • Improved energy levels – The sugars and carbs in bananas will boost your rat’s energy levels, allowing it to become more active during the day. Nobody hates an energetic and playful rat, especially when the rodent has mates to share the joy with.
  • Digestive improvements – Bananas contain a fair amount of fiber. A medium, ripe banana has approximately 3 grams of fiber which aids in digestion. Fibers are great for constipation but can actually cause constipation when it excess. Diarrhea is also a potential effect of excess fibers, so portion the fruit carefully throughout the week to prevent that.
  • Improved organ functioning – Bananas contain potassium, magnesium, and vitamin C, which are all necessary for improved organ functioning. The fruit is also great for lowering bad cholesterol, essentially protecting the rat against obesity-related health problems.

It also doesn’t hurt that bananas are delicious, and your rats will love eating them. Good food is known to increase the rats’ spirits just as they do in humans.

How to Feed Bananas to Pet Rats?

Some people use bananas in shakes, but I advise against it. Your rats should never drink their calories but, instead, eat them in solid form. This stays true for humans as well. Liquid calories are easier to digest and absorb, so they won’t keep the rat satiated for long. This will cause the rat to get hungry sooner, which leads to overeating, obesity, diabetes, and so on.

Instead, I recommend 2 better options:

  1. Raw bananas – Simply peel the banana, cut it in slices, and feed it your rat. The rat will grab the slices individually and eat them one by one. This feeding method allows you to portion the banana properly to make sure your rat only eats what it’s supposed to eat. You can store the rest in the freezer and give it to your rat the next day, but that’s rather unlikely to work. Bananas oxidize fast when in contact with air.
  2. As a mixed paste – You can mix a bit of banana with other fruits, nuts, peanuts, or anything else that your rat could eat. Blend everything together, portion the paste and place it in a freezer until it solidifies. You can then feed your rat one portion at a time over the course of several days, naturally, as part of a diverse diet. Your rats will love the crunchy banana paste.

Regarding the latter point, consider the amount of banana to add to the paste carefully. The same goes for all of the different foods, like apples, nuts, veggies, grains, or whatever other ingredients you plan on adding. It’s more difficult to appreciate the correct feeding amount of a certain food when it’s mixed with others.

Can Rats Eat Banana Peels?

Yes, they can, but I wouldn’t advise it. Unless you actually have a banana tree in your backyard, don’t feed banana peels to your rats. That’s because most bananas have been treated with pesticides, and these chemicals infiltrate in the peel. They won’t reach the pulp, which is good news, but the peel is dangerous and unfit for consumption.

Unless, of course, your bananas haven’t been treated with anything, which is highly unlikely.

The problem is that even if the banana is pesticide-free, you still have the fiber content to worry about. The peel contains a lot more fibers than the pulp, and excess fibers can cause constipation, diarrhea, and other digestive issues that won’t sit well with your rat.

Can Rats Eat Banana Bread?

Absolutely, they can, but there’s a catch. Where you’re sourcing the bread itself matters a lot. I say stay away from commercial banana bread due to the high sugar content, which is so prevalent in any commercial bread. These products also contain various additives that your rats may not appreciate as much.

Instead, make some banana bread at home. It won’t take too much of your time and will provide your pet rat with a readily available and delicious snack. You can place the bread in the fridge and cut some of it in smaller treats for your rat to enjoy.


Bananas are awesome for pet rats, but only in small portions. As with anything, moderation is what makes differentiates between good and harmful.
