Can hamsters eat water chestnut, and why?
Only a tiny piece of plain water chestnut for hamsters, if at all. Starchy and not a natural food.
Hamsters are omnivores who do best on a complete hamster mix, with small amounts of fresh food as treats. They are tiny and prone to obesity and diabetes (especially dwarf hamsters), with sensitive tummies, so portions must be minimal and sugary or watery foods limited.
Warning — what to watch for
Starchy and not a natural food.
