Can hamsters eat bananas?

Yes, but only now and then. Banana is not toxic, but it is one of the most sugary, starchy fruits. A raisin-sized piece once a week at most, with no peel. For a Russian dwarf hamster, which is prone to diabetes, keep it to an occasional treat.

How much banana, and how often

  • Amount: a raisin-sized piece. A whole slice is already a lot for a dwarf hamster.
  • How often: once a week at most; for a dwarf, once a fortnight.
  • How: ripe but not overripe, peeled, raw.
  • Never: fried banana, banana chips, smoothies or sweetened purées.

Why so little

Banana is high in calories and sugar. Too much is fattening, can push dwarf hamsters towards diabetes and, being soft and sticky, can stay in their cheek pouches or rot in their larder. Take away anything left after a few hours.

Food in Nibbly

In Nibbly you choose what goes in the bowl: seed mix, which keeps their weight, veggies, light and with a little water, or sunflower seeds, which they love but which are fattening. Overfed hamsters get chubby, and treats from your hand help you earn their trust. Everything they eat is in the feeding guide.

Frequently asked questions

Can hamsters eat banana peel?

Best not: it is tough, hard to digest and often carries traces of treatments. Give only the flesh, in a small piece.

Can dwarf hamsters eat bananas?

Yes, but even less than other hamsters: a small piece once a fortnight. They are prone to diabetes, and banana is one of the sweetest fruits.
