Can hamsters eat olive oil, and why?
Only a tiny drop of olive oil, if any, for hamsters. Fat is unsuitable in anything but the tiniest amount; not a needed 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.
