Can hamsters eat granola, and why?
Shop granola is best avoided for hamsters because of the sugar and raisins. The added sugar and any raisins or chocolate make it unsuitable; plain rolled oats are safer.
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
The added sugar and any raisins or chocolate make it unsuitable; plain rolled oats are safer.
