Quick verdict

Caution

Can hamsters eat breakfast cereal, and why?

Only a few bits of plain, sugar-free cereal, if any, for hamsters. Avoid all sugary or chocolate cereals; plain puffed wheat or oats in tiny amounts only.

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

Avoid all sugary or chocolate cereals; plain puffed wheat or oats in tiny amounts only.

If your hamster has eaten breakfast cereal, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
