Can Guinea Pigs Eat Eggs_

Everybody that has a guinea pig has been at least once tempted to feed the cavy with some tasty foods that we humans eat. Guinea pig owners know how cute it is to give the little furball something new to eat but not every type of food is safe for them. In this article, we will explore a very common food that most people have in their breakfast, and naturally, we are talking about the eggs.

Most people love eggs as there are many ways to prepare them for example sunny-side-up, scrambled, poached, boiled eggs, and so on. But, are eggs healthy or tasty for the cavies? We have to keep in mind that guinea pigs are herbivore animals and eggs certainly don’t fall into the list of safe foods for their diet. Nevertheless, let’s find out more about guinea pigs and eggs.

Can guinea pigs eat eggs? Guinea pigs can’t eat eggs because they are herbivore animals, which means that their digestive system is not designed to process foods such as eggs. They can eat roots, herbs, leafy greens, veggies, fruits, and even some flowers. Their diet mainly consists of hay, pellets, water, and occasional leafy greens and fruits.

Eggs are known to be very healthy and beneficial for humans, but why is this food so harmful to guinea pigs? In the following sections, find out what are the possible risks if you give eggs to guinea pigs. Let’s begin!

Risks of Feeding Eggs to Guinea Pigs

Risks of Feeding Eggs to Guinea Pigs

Considering that there are not enough beneficial nutrients in eggs and no health benefits of feeding eggs to guinea pigs, in this section, we will take a look at the most important risks.


Bad for Digestion

As we have already said, guinea pigs are herbivores, and they have a sensitive digestive system that is made for processing only plant-based foods. They shouldn’t consume any food that comes from other animals such as milk, cheese, or meat. Also, there are no dietary fibers in eggs, and without fibers, their digestion will be slower and more complex, considering that fibers help guinea pigs to have easy and fast digestion.


Cardiovascular Problems

Even for humans, too many eggs, or having eggs every single day is not recommended. This is mainly because of the amount of cholesterol and fat in eggs. Cholesterol and fat are needed for some basic functions in the body, but they still increase the risk of cardiovascular problems and can damage the blood vessels. The amount of cholesterol and fat in eggs is simply too high for guinea pigs to handle.


Urinary Problems

The most damaging risks of eggs are the calcium and sodium levels. This is what makes eggs very unhealthy food for guinea pigs. These amounts of calcium and sodium in eggs aren’t good for guinea pigs because calcium together with sodium can create urinary problems such as stones in the bladder or kidneys. Otherwise, calcium is good for healthy and strong bones, but for adult guinea pigs, this mineral is not useful.


No Vitamin C

Eggs have no vitamin C. Without it, guinea pigs can get a disease called scurvy. The symptoms of this disease are the following: rough coat, swollen joints, internal bleeding, no appetite, and so on. Vitamin C is an essential nutrient for guinea pigs because they can’t produce it in their bodies, and they need different foods that have a good amount of this vitamin in order to lead a healthy life.
