Why is My Guinea Pig Not Drinking Water?

Sometimes guinea pigs will have a decreased water appetite. However, refusal to drink water is not normal and might be a sign of more underlying conditions like physical or mental trauma. Try observing your pet more carefully to determine the problem and adjust accordingly.

Causes of Decreased Water Appetite in Cavies

 Stress and anxiety: When you pet is stressed or anxious, it hides away and loses interest in most things. This includes eating and drinking water.

Injury or pain: A hurting guinea pig will want to lie around and probably won’t move around to drink water.

Respiratory infection: Guinea pigs are prone to diseases like cardiac disease and bacterial pneumonia. This may result in a decreased water appetite.

Dental problems like cheek teeth elongation or gum problems. This makes it hard for them to be able to drink or eat anything.

Gastro intestinal problems e.g. ulcers, bloating etc. In such cases, the guinea pig will hardly drink water.

Urinary tract infection in cavies: When they have these infections, they urinate less often. This will result in more water being retained in their bodies therefore they drink less.

Feeding your cavy with water that has high chemical levels e.g. chlorine.

Changes in environment: New pets are at first afraid and anxious. This makes them to hide away and will only come out to take water when you are not around.

Other factors which are not fatal include;

a). Changing the diet: When more fruits and vegetables are incorporated into your cavy’s diet, it will not require a lot of water.

This is because fruits and vegetables are succulent therefore they have high water content and will meet the water requirements of your pet.

b). Weather condition changes: During cold weather, guinea pigs might not drink a lot of water since they are not losing much.

Right Water Amounts for Guinea Pigs

Inadequate water intake in guinea pigs leads to dehydration. When cavies are dehydrated, they could die within a period of twelve to forty eight hours. Ensure that your pet is taking water in the right amounts.

A single guinea pig should drink at least eighty to a hundred milliliters of water per day. However water intake in guinea pigs varies depending on age, weather conditions and the stage of production.

Younger guinea pigs will drink less water since they get most of it from the mother’s milk.

During hot temperatures, guinea pigs will drink more water to replenish the lost amount.

Moreover, lactating and pregnant guinea pigs require more water content. Milk production in lactating guinea pigs requires water thus the high water intake.

Water Feeding in Guinea Pigs

How you offer your pet water and the water given influences its ability to drink the water. Sometimes, the guinea pig will refuse to take water because of issues on your end. So, what is the right water routine for these pets?

Have more than one water bottle in your pet’s cage. For many cavies in one cage, have more water bottles so that each has an opportunity to take water.

Clean the water bottles daily and replenish them with fresh water. Dirty bottles will likely have blocked nozzles.

Ways to Encourage Guinea Pigs to Drink Water
