Can Rats Eat Bananas? What You Need to Know

Social, intelligent, and affectionate, the rat is a popular pet choice in the United States. They bond with their owners and can even be taught to do tricks. Inviting a rat to share your home can be a rewarding experience as you enjoy their entertaining and friendly personalities. The best way to ensure that you give your rat a healthy and happy life is to meet their needs, including dietary requirements. Most rodents are known to love cheese, but many also enjoy a diet of various fruits and vegetables. Rats are not known to refuse anything that’s offered to them, including bananas.

Humans love this fruit as a daily treat, but can a rat eat bananas too? The short answer is yes, rats can safely enjoy bananas. Let’s look at when it’s safe for them to eat bananas and how much of the fruit they can eat.


What Is Safe for a Rat to Eat?

Rats are omnivorous creatures. They eat fruits, vegetables, and meat. They like to eat anything, so it’s important to know what will provide them the best nutritional value. A pelleted rat food will usually consist of protein with other vitamins and minerals. This is a good option for making sure your rat gets what they need, but pellets should always be combined with other things. Rat food offered with a mix of fresh fruit and vegetables will keep rats the healthiest that they can be.

In addition to bananas, things that are safe to give your rat as part of their diet include:

  • Apples
  • Small cooked pieces of meat or eggs
  • Berries
  • Carrots
  • Broccoli
  • Corn
  • Peas
  • Melon

Certain foods are toxic to rats and should always be avoided, like:

  • Caffeine
  • Chocolate
  • Raw beans
  • Raw sweet potato
  • Lemons
  • Mango

Are Bananas Ever Unsafe for Rats?

Bananas are best when offered to your rat as a treat or a small part of their diet. While they are safe for rats to consume, you’ll want to avoid giving them bananas that are underripe and green. It’s harder for rats to digest underripe bananas, and this can lead to stomach aches and illness. To avoid causing your rat any unnecessary discomfort, always make sure the bananas that you offer are yellow and ripe.

How Many Bananas Can Rats Eat?

Bananas are full of vitamins, minerals, and other good stuff that can keep your rat healthy. Plus, rats find them delicious. Still, it’s actually better to serve this fruit to your rat in moderation.

You can mash up the banana or offer it in slices. Your rat may prefer the mushy texture that comes from mashing. A few slices offered once a week will provide just enough of a tasty treat. Bananas are naturally high in sugar, so too many of them can lead to obesity.

While the fiber that bananas offer helps keep your rat’s digestive tract healthy, too much can have a reverse effect. Excessive amounts of fiber can lead to constipation, diarrhea, and stomach upset.

Are Bananas Good for Rats?

Bananas, aside from being delicious, are full of beneficial things to humans, so it makes sense that they’d be beneficial to rats too. Magnesium, vitamin C, and potassium can keep your rat’s internal organs functioning well. The banana pulp can even lower a rat’s cholesterol. Some rats like to eat slices of banana still in the peel. While the peel is non-toxic and safe for your rat to eat, be aware that it can contain pesticides. To be safe, avoid giving the peel altogether, or make sure it’s thoroughly washed before you offer it to your rat.

Use the Banana as a Treat

Another way to feed a banana to your rat is to only use it during training. If you’re teaching your rat a new trick or trying to get them to curb an unwelcome behavior, use the banana as the incentive and reward. If this is a treat only offered during training times, your rat is much more likely to perform the desired task or behavior when they know that a rare tasty reward is waiting for them.



While bananas are safe for rats to eat, only feed your rat yellow, ripe bananas. Avoid green and underripe bananas because they can cause digestive discomfort. Offer your rat just a few slices of banana each week to allow them to get the benefits of the vitamins and minerals it offers without too much added sugar, which can lead to obesity. Bananas can be part of your rat’s diet as a healthy and tasty treat that your rat will love.
