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

But they also contains a lot of water which is not good for guinea pigs.

Due to the amount of acidic content and water that onions contain, they will unfortunately make guinea pigs sick if they eat them.

They just can’t handle the nutrients that they contain.

Too much water will bloat a guinea pig and too much acidic content will cause their stomach to become upset.

This means that not only raw onions, but it would be worth avoiding other variations such as red onions, spring onions, pickled onions and green onions as they have similar nutrients.

They also cannot eat cooked onions as cooked foods are not good for guinea pigs.

Just a final note.

Although I have never tried feeding onions to my piggies, I don’t think they would attempt to eat them due to their pungent smell, they always give food a good sniff to check it out and my piggies are quite picky about what they eat.

In my experience, guinea pigs are quite smart about knowing what they like and don’t like, which is pretty good for us owners if we decide to feed them food which isn’t good.
