Why are Onions bad for Hamsters?

This is because of the high acidic, salt, sugar, and water content in onions. All of these elements are extremely dangerous for hamsters. Plus, their taste is too pungent and strong for hamsters anyway.

And that is not all. Actually, onions contain a compound called thiosulfate. This can have extremely adverse effects on your hamsters’ health. Basically, thiosulfate results in a condition called hemolytic anemia. In this condition, your hamster will start losing its’ red blood cells quickly. This can become fatal for your pet, especially in hamsters as their little bodies simply can’t cope with it.

The strong chemicals present in onions can even cause gastroenteritis in your pet and are generally toxic for most animals.

For these reasons, onions are a big no-no, for not just hamsters but also dogs, rabbits, and cats.
