As you can see onions contain a little phosphorus, calcium, a lot of acidic content and water and sugar.

This means that unfortunately they can’t eat onions at all. They just cant eat food with high amounts of acidic content and water, they will make them sick if they eat them.

A food to avoid for all species of hamster, including Syrians and Roborovski’s as they are just too acidic even for them.
