It’s important to give rodents a variety of fresh foods. But we always want to ensure what we’re feeding is safe for them! You might wonder, can hamsters eat bananas?

Most healthy adult hamsters can eat a small piece of banana once to twice weekly without a problem. However, baby hamsters and dwarf hamsters may do best without fruit in their diet.

If you ever have questions about your specific hamster, please consult with your veterinarian. This is even more important if they have dietary restrictions or a chronic illness such as diabetes.

Hamsters can eat bananas safely, but they contain a lot of sugar that isn’t good for them in excess. So, hamsters should only eat tiny pieces of banana once to twice a week at most.

Fruit isn’t a necessary part of a hamster’s diet but instead should be used as an occasional treat. The majority of your hamster’s diet should consist of a dry food mix, insects, and dark, leafy greens.

Too much banana may lead to stomach upset, diarrhea, or high blood sugar.

Can Dwarf Hamsters Eat Bananas?

Dwarf hamsters tend to be more sensitive to sugar than other species. Chinese dwarf hamsters, in particular, are very prone to diabetes.

Avoiding sugary foods like fruit altogether is a good choice if you have a dwarf hamster. Alternatively, you can feed fruit like bananas but very infrequently and in tiny amounts–such as ¼-½ the serving you’d give to a larger hamster species.

Banana peels themselves are hamster-safe, but they may contain pesticides that are toxic.


Hamsters can eat banana peels, but keep in mind that they usually contain pesticides. Wash them thoroughly and cut them into very small pieces before serving.

Another note is that banana peels are porous, so pesticides can soak through them and even onto the fruit itself in small quantities. This doesn’t make bananas unsafe, but it might mean that the peels are better off tossed in the compost.

Like banana fruit, the peels should only be fed in limited quantities as treats. Some hamsters will ignore the peel and opt for the fruit instead–after all, it’s just not as tasty. There’s a reason humans don’t typically eat them!

Hamsters can eat a small piece of banana one to two times a week, so long as they aren’t also getting other fruit. Dwarf hamsters should be fed little to no bananas in their diet, and baby hamsters under three months old shouldn’t eat fruit at all until they’re older.

How to Prepare Bananas for Your Hamster

The key to serving bananas to a hamster is to feed only small quantities.


  • Peel a fresh banana. Ideally, it won’t be over-ripe, as brown bananas contain more sugar than yellow or green ones.
  • Cut off a slice of banana, then dice it into small cubes.
  • Feed your hamster one small cube of banana. Share the rest with other pets or humans in the family!

If feeding banana leaves or peel, be sure to wash them thoroughly and chop them into tiny pieces. Feed them in small amounts only.

Avoid feeding your hamster processed human foods with bananas in them, cooked bananas, or any sauces or seasonings on the banana. Plain, fresh banana is best!

Which Fruits Can’t Hamsters Eat?

Hamsters should never eat eggplant since it’s toxic to them. Also, watch out for pits and seeds–some are completely safe, but others are toxic.

Examples of fruit seeds and pits to avoid include cherry pits, apple seeds and pits, and pear pits and stems.

Tomato leaves and unripened tomato fruits are also toxic.
