How to Feed Water to 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 guinea pig 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.

How do guinea pigs drink water?

Guinea pigs should drink water out of a glass or plastic bottle that is specially designed for small pets. The bottle can be attached to the outside of the cage or hutch with a bendy metal fastener or spring 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. Alternatively you can buy a glass bottle which is much longer-lasting and better quality too.
