Need to know the answer to can Guinea Pigs Eat Onions? Although some less informed individuals may say that small amounts of onions are okay to feed your cavy, you should never give your guinea pig onions. No, guinea pigs cannot eat onions. They cannot eat spring onions either. Both are very poisonous to your guinea pig. Even in small quantities, they can have a negative effect on your guinea pig’s health.

Some pet owners state that guinea pigs can eat the green tops off of green onions, but that you should not feed them the bulb part of the onion. However, based on the fact that the bulb part of the onion is poisonous to your guinea pig, we suggest that you simply avoid onions entirely. Overall, this will be safer for your cavy. If you want to keep your guinea pig healthy and happy, you should find another vegetable to feed them instead of onions.

Onions are harmful to guinea pigs because they contain the compound disulphide. This compound can harm your cavy’s red blood cells and can ultimately destroy the cells’ ability to carry oxygen through your guinea pig’s blood stream. This can cause your guinea pig to become weak and anemic. It can also limit your guinea pig’s ability to breathe correctly. This can be fatal to your cavy if it becomes too severe.

So, can guinea pigs eat onions? No, they should never eat onions. Onions have no real nutritional value and can be very detrimental to your cavy’s health in the long run. Therefore, you should keep onions away from your guinea pig. If you want to diversify your guinea pig’s diet, then you should try feeding them one of the many vegetables or fruits that are approved for cavy consumption.
