Can hamsters eat lemon, and why?

Do not give lemon to hamsters. The acidity is harmful to such a small animal and can cause mouth and stomach irritation.

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

The acidity is harmful to such a small animal and can cause mouth and stomach irritation.

If your hamster has eaten lemon, 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.
