Water for Guinea Pigs

Water is an important part of your guinea pigs diet and should be replaced daily to ensure it is free of bacteria. 

Water should not be distilled and should be free from any contamination (so, that means filling up at the kitchen sink and not the garden water butt). You should not need to supplement their water with any vitamins or minerals if the food you are providing contains enough vitamin C. 

Changing the water daily, as opposed to simply topping up, will also allow you to monitor just how much water your cavy is drinking. Any changes in their intake could indicate an underlying medical condition.

You must wash the water bottle thoroughly on a daily basis before re-filling.

FAQs About Water for Guinea Pigs

Here are some answers to frequently asked questions about water and guinea pigs.

How Do Guinea Pigs Drink Water?

Guinea pigs drink via a plastic bottle with a metal non-drip mouthpiece. It is attached to the outside of the cage with a bendy metal fastener.

Plastic water bottles degrade over time so you should replace their bottle every year to make sure they are getting the best quality care.

How Much Water Should Guinea Pigs Drink?

They need a constant supply so don't limit their water. On hot days they will drink more than cold days. Also, it depends on the food they are eating. If they are eating a lot of water based food they may not drink so much.

Can Guinea Pigs Drink Water Out of a Bowl?

Guinea pigs can drink water from a bowl but it isn't hygienic as it can become contaminated with urine and faeces. You should always ensure you have a proper water bottle feeder for your pet so they have access to clean water.

Can Guinea Pigs Drink Tap Water?

Yes, this is exactly what you should be giving them. Don't give them water from anywhere else.

Can Guinea Pigs Drink Cold Water?

Yes, you should always give them cold water but it shouldn't be chilled. Straight from the cold tap is fine.

How Long Can Guinea Pigs Go Without Water

You should never leave your guinea pig without water. It is an essential part of their diet and without it they will quickly become dehydrated and ill.

My Guinea Pig Isn't Drinking Any Water

If your guinea pig isn't drinking the water, check the bottle is actually dispensing the water properly. If the water bottle is working correctly and they are still not drinking, contact your vet as your guinea pig may be unwell.


In summary, good clean tap water is vital for your guinea pig. It needs to be changed daily and should be dispensed in a plastic guinea pig feeding bottle fixed to the side of the cage.
