Can hamsters eat pizza, and why?
Pizza is far too salty and fatty for hamsters. Salt, fat, dairy and seasoning are dangerous.
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
Salt, fat, dairy and seasoning are dangerous.
If your hamster has eaten pizza, 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.
