Listed below are some of the possible reasons why your guinea pig drinks much water.


#1. Season

With every changing of seasons, animals tend to change their cycle of needs too. They might need to eat a lot before winter, preparing themselves for hibernation in some animals.

Some may need to drink a lot of water during the summer season because of the hot weather.

This is the case with your guinea pig. Especially in summer, the weather gets hotter, which is one reason why your guinea pig drinks a lot of water.

They might be drinking too much water to keep their body hydrated or to keep themselves cool.

The Guinea pig age, size, diet, exercise, and lifestyle could be one of the factors.

Reasons Why My Guinea Pig Drink A Lot Of Water

Well, most of us guinea pig owners tend to get concerned about how our precious little pets are eating, so this matter is a serious thing for us. Some guinea pigs tend to drink from 80 ml to 150ml of water.

Do not compare your guinea pig with others because every guinea pig varies. Observe their usual water intake, and if you see a drastic change, then that is the time you should worry about why.


#3. Change in diet

A change in diet could also be one reason why your guinea pig had a sudden change in water intake.

But that sudden change could lead to diarrhea and loos of essential electrolytes from their body.

The lack of vegetables in their diet could be a determining factor in their thirst. Guinea pigs are fussy eaters, but they could get a sufficient amount of water from what they eat.

Although hays are the most recommended food for these types of pets, vegetables should never be absent in their diet.

Vegetables keep a well-balanced diet in their body. A lack of vegetables in their diet could trigger excessive thirst.

As well as the amount of salt in their food. Excessive salt could lead to dehydration.

As salt absorbs water from their cells, leaving them completely dehydrated, keep watch of the salt intake.


#4. Pain

Guinea pigs are one of the prey animals that tend to hide away their pain. This is to help them survive in our ecosystem.

However, this behavior becomes a challenge to us pet owners as we will not know what our pets feel, especially when they’re suffering from any pain. (please read here why does Guinea pig lick me)

#5. Diabetes

Diabetes is a common disease in guinea pigs. Too much treat is one of the main causes of this disease.

So if I were you, I would prevent myself from falling for those cute little gestures and give them a manageable amount of treatment that they deserve.

Guinea pigs can be diabetic by birth, but that is a rare case. In most cases, an unbalanced and poor diet leads to diabetes in guinea pigs.

If you see your guinea pig increasing their appetite, frequently urinating, and drinking water excessively, these are common symptoms of diabetes.

Remedy: See your attending veterinarian for medical attention. Switching their diet to a healthy one could be a good idea also.
