Guinea pigs should drink water every day, but what if they drink too much, is it dangerous for their health?

If guinea pigs drink too much water it can cause health problems. They do drink a lot of water at certain times, for example when it is very hot which is completely normal.

But sometimes they know how to drink too much water and when they are sick if they have diabetes or problems with their kidneys.

In today’s article, we will find out what are the reasons why guinea pigs drink too much water, as well as the problems they may have.

Why do guinea pigs drink a lot of water?

Guinea pigs drink a lot of water for many reasons such as changes in diet, dehydration, overheating, diabetes, and others.

So let’s take a closer look at each of these reasons and how they influence the guinea pig to drink more water.


When guinea pigs have diabetes they drink water all at once and have no appetite.

Diabetes in guinea pigs can be due to poor nutrition, and sometimes it can be a genetic disease, but most often food is the cause of this disease.

Type 2 diabetes is most common in guinea pigs and usually occurs when they are one year old.

When guinea pigs have diabetes, apart from drinking a lot of water, can be noticed other symptoms, such as the following:

  • occurrence of cataract
  • weight loss
  • urinary tract infections
  • frequent urination

If you notice any of these symptoms, it is necessary to take your pet to a veterinarian to prescribe appropriate therapy for treatment.

Of course, it will also be necessary to change the diet of your pets.


Dehydration in guinea pigs leads to frequent drinking of water.

We must say that dehydration in guinea pigs is mostly related to the temperature in the environment of the guinea pig.

When a guinea pig is warm it drinks more water which is completely normal.

Guinea pigs have thick fur that warms them even more, so we must pay attention to the temperature in the environment.

When guinea pigs are dehydrated it can be much more dangerous than just drinking more water, they can die from dehydration.

The diet

Changes in the diet of guinea pigs cause them to drink more water than usual.

Guinea pigs are herbivores that eat only plant food, but sometimes we can mistakenly give them food with too much sugar in its composition, or with too much salt and fat, which affects the guinea pig and make it drink more water.

That’s why when we start giving them some new food, we have to pay attention to how our pets will act, will they drink more water?

For example, if we give them food that does not have so much water in its composition, they will drink more water, while, for example, vegetables have enough water in their composition, and guinea pigs will not need to drink too much water.

Guinea pigs should eat 80% hay in their diet, which is no coincidence because hay also provides them with enough water that they need.why guinea pig drinking lot water


When guinea pigs are bored they start to get stressed and depressed which eventually results in drinking more water.

Guinea pigs are very smart animals and if they don’t have enough toys, activities, and places to play and climb, they soon lose the desire for mental stimulation, and then the problems we mentioned begin.

From our side, we should always provide them with enough activities so that they don’t get bored, buy them new toys, and simply do certain novelties to make it interesting for our pets.


In addition to other reasons for drinking more water, diseases are one of the possible reasons that lead to water problems in our furry friends.

Various diseases can cause guinea pigs to drink more water, here are some of them:

  • dental problems
  • problems with the urinary tract
  • gastrointestinal problems
  • blisters on the feet

These are just some of the possible problems and diseases that cause the guinea pig to drink too much water due to pain.

Sometimes it’s a little hard to notice that they really have a problem because they usually hide illnesses and pain.

They do this because this is how they are taught in nature, not to show signs of illness or injury, because they will more easily fall prey to predators.
