Can hamsters eat caffeine, and why?

Never give caffeine to hamsters. Highly toxic stimulant for such a small animal.

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.

If your hamster has eaten caffeine, 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.
