Can hamsters eat peanut butter, and why?

Only the tiniest smear of plain peanut butter, if at all. Very high in fat and sticky, which can clog cheek pouches; must be xylitol-free.

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

Very high in fat and sticky, which can clog cheek pouches; must be xylitol-free.

If your hamster has eaten peanut butter, 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.
