They are too acidic!

Onions contain a lot of acid, so much that they cause acid reflux in humans! Humans can deal with problems such as acid reflux, and other problems with acidic foods, but hamsters cannot! Hamsters have a very fragile digestive system, that simply cannot deal with acidity. It can lead to stomach upset, and severe illness and pain for your hamster. Stay away!

Thiosulfate is a substance that is contained within onion and would be ingested by your hamster if they eat it. They cannot digest this, and this causes huge problems for your furry friend.
