Can hamsters eat croissant, and why?
Croissants are best avoided for hamsters. Too rich and buttery, and soft dough can clog cheek pouches.
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 rich and buttery, and soft dough can clog cheek pouches.
