What Happens If My Guinea Pigs Eat String Cheese?

Feeding them processed diets like cheese will cause serious health problems like diarrhea, vomiting, bloating, and more.

Giving your pets cooked meals is not advisable too.

Although a small slice of these snacks may not cause harm. But if you continue to feed your cavies cheese every day, they won’t live long. 

This will result from the damage to their internal organs over time. 

It is better to consider your guinea pigs’ overall health when feeding them any diet.

Below are the possible risks of feeding cheese to your cavies:

Risk in Feeding String Cheese to Guinea Pigs

Let’s just say cheese adds no dietary value to the health of your guinea pigs. On the other hand, it causes health issues in your little furry friends. 

So, below are the risks you’ll be exposing them to if they eat cheese:


Usually, cheese contains high calories. No doubt, your guinea pigs will become obese if they eat the snacks regularly.

Although a small amount of calories is healthy for cavies, it shouldn’t be from cheese. Naturally, the diet contains too many calories that even a small piece can be dangerous.

An obese guinea pig is usually inactive due to too much weight. In the long run, it will likely be exposed to the risk of other diseases and even predators. 

Understand that there is a big difference between eating healthy to gain weight and being obese. 

Therefore, if your guinea pig is suddenly gaining excess weight, you should consult your vet doctor


Regularly serving your adult guinea pigs string cheese can cause indigestion. This will then result in bloating, diarrhea, stomach pain, and other discomforts. 

Like all dairy products, string cheese contains lactose. Unfortunately, adult guinea pigs cannot digest this nutrient because they don’t produce lactase.

However, baby guinea pigs can produce lactase to digest their mother’s breast milk.

Cheese is a strange diet for your small pets that you should not give them.

Urinary Problems

Among the rich nutrients found in string cheese are calcium and phosphorus. These two properties can cause bladder and kidney stones in your guinea pigs when in excess. 

Urinary problems are the result of these two serious health problems.

Painful urination, bloody urine, and urinary tract infection are the common symptoms of bladder and kidney stones. 

Never allow your small pets to experience a problem like this; they may not survive it.

Heart Problems

String cheese is a great source of fat, cholesterol, and calcium. If your guinea pigs eat them in excess, they may have cardiovascular problems. 

Cholesterol and fat, for example, can prevent the free flow of blood to the heart. Too much sodium can also increase the blood pressure of your guinea pigs. 

As you know, the heart is a major organ of the body. Therefore, avoid anything that can harm your guinea pigs.
