Onions can be toxic for guinea pigs and if you feed them in any form, they can kill the poor pet.

What Is In Onions That Affect Guinea Pigs

Here is a detailed description of the compounds found in onions that can adversely impact guinea pigs.

Thiosulfate: Thiosulfate is a compound of hydrogen, sulfur, and oxygen. The acidic, and sulphuric aroma of onions is due to this compound. Guinea pigs cannot consume this compound as it can be hard for their digestive system and may even give them terrible stomachache and diarrhea in extremely small amounts. Since onion has thiosulfate in larger quantities, it can be harmful to them and may impact them in a single dose.

Disulfide Compounds: These compounds are also extremely toxic and can harm guinea pigs’ digestion drastically. If you are feeding onions in any cooked food, it can still be harmful to guinea pigs. The best way to ensure the health and strong gut of your rodent pets is to abstain from feeding them onions in any way.

When guinea pigs become obese, they stop being active and stay in one place. This may lead to a lack of appetite and may even make them ill.

Calcium: Calcium is necessary for all living creatures, but an excess of this mineral can make guinea pigs develop bladder and kidney stones. It is best to feed these rodents vegetables and fruits that contain adequate amounts of calcium and not a high quantity of this mineral.
