Can hamsters eat olives, and why?
Olives are best avoided for hamsters because of the salt and oil. Too salty and fatty for such a tiny animal, and brined olives are worse still.
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
Too salty and fatty for such a tiny animal, and brined olives are worse still.
