What Happens if Hamsters Eats Onions?

If a hamster eats onions, it can negatively affect its little body. 

First, onions can upset a hamster’s tummy. Just like when you eat something that doesn’t agree with your stomach, and it feels uncomfortable, the same thing can happen to a hamster. 

They might feel sick and have an upset stomach.

Second, onions can give hamsters diarrhea. Diarrhea means they might have watery or runny poops, which is not fun for them. It can make them feel weak and uncomfortable.

But the most serious thing that can happen is damage to their red blood cells. Red blood cells are really important because they carry oxygen all around the body. Onions can make it harder for the red blood cells to do their job properly, and this can make the hamster very sick.

These include things like carrots, apples, or cucumbers. Just remember to cut them into small, bite-sized pieces so the hamster can easily eat and digest them.
