They don’t try to think what they are feeding their guinea pig is suitable for their health or not.

The problem is that not every food is the same; not every food we eat is suitable for our pets.

For example, green onions are one of the vegetables that are available to everyone in their kitchen.

So, without thinking much enough, they give these onions to their guinea pigs, and soon, when their guinea pig got seek, they wondered why this happened.

If you want to prevent your guinea pig from this disease, you have to give them certain foods containing enough vitamin C.

For example, daily, they need 30 – 50 mg of vitamin C.

What Risks Should You Avoid?

Before you ever decide to feed green onions to your guinea pigs, you should watch out for a couple of things.

It would be best if you did not feed green onions to your guinea pigs in excess.

It’s because those green onions that you are feeding your guinea pigs contain calcium.

Now calcium is a good mineral for our bones, but for your guinea pigs, it’s a problem.

As I said before, you have to feed only leaf parts of green onions.

However, it would be best if you remembered, and you have to give these green onions in little amounts.

It’s because an excess amount of these green onions overflow calcium in your guinea pig body.

Therefore, it leads them to cause some painful problems like kidney or bladder stones.

So, these problems cause your guinea pigs to have bloody urine, painful urination, and even renal failure.

Not only that, an excess amount of green onions overflow fibers in their stomach, and it will lead them to some serious issues such as loose stool, gas, diarrhea, and flatulence.

Besides the fact that these green onions have nutrients that give your guinea pig some profound health benefits, it contains a big sugar chunk.

First, you have to understand your guinea pigs don’t have a strong digestive system as we have, and their metabolism is not designed to process a big chunk of sugars at one time.

In fact, their digestive system is so sensitive that you have got to be serious about their diet.

So, to help you do that, we have selected several foods that you have to eliminate from your guinea pigs’ diet.

Foods You Should Never Give Your Guinea Pig To Eat

Like many other pets, also guinea pigs are not keen on some particular types of food.

For example, chocolate and other “human treats,” dairy products, meat, corn, iceberg lettuce, tomato leaves, potatoes, anything that has sugar, rhubarb, raw beans, and multi-vitamins.

Each of the foods in the above list is a big no for your guinea pigs.

These foods can cause some severe problems if you give them food, so make sure you avoid these foods no matter what.

Okay, that was the list of foods that you have to avoid.
