Can hamsters eat oat milk, and why?

Hamsters should only drink plain water, not oat milk. Plant milks are unsuitable 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.

Warning — what to watch for

Plant milks are unsuitable for such a small animal.

If your hamster has eaten oat milk, 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.
