Can hamsters eat kidney beans, and why?

Only a tiny amount of fully cooked, plain kidney bean for hamsters, if at all. Raw or undercooked beans contain toxic lectins and even cooked beans can cause gas.

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

Raw or undercooked beans contain toxic lectins and even cooked beans can cause gas.

If your hamster has eaten kidney beans, 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.
