Can hamsters eat peaches?

Yes, in small amounts

Yes, in small amounts. Peach flesh is listed as safe for hamsters, but the stone, leaves and stem contain cyanide-releasing compounds, and the fruit is sugary.

Portion: A piece about 1 cm (⅜ in) across, no bigger than your hamster's ear, for a Syrian; about 5 mm (¼ in) for a dwarf.
How often: Once a week (twice at most) for a Syrian; no more than once every two weeks for a dwarf.
Dwarf hamsters: Campbell's, Winter White, their hybrids and Chinese hamsters are prone to diabetes. Give peach only rarely, as a 5 mm (¼ in) taste no more than once every two weeks, or skip fruit and use a low-sugar vegetable such as cucumber as a treat. Roborovskis are less studied, but they are tiny, so keep their portions just as small.
Sugar: 8.4 g / 100 g

How to serve it

Wash well
Remove the stone, stalk and any leaves
Cut a small piece of ripe flesh; washed skin can stay on
Remove any uneaten piece, including from the hoard, within a few hours

Why

Risks. The stone, stem and leaves contain cyanogenic glycosides. The flesh is sweet and juicy, so too much can cause soft droppings and weight gain.

Benefits. Juicy and a source of some vitamins and fibre.
