Guinea pigs do need to drink fresh water on a regular basis to stay healthy but what type of water should be given to them?
The best news is that the free cold tap water is the best type of water to be drank by your guinea pig.
Therefore to answer the question – can guinea pigs drink cold water, YES.
The great thing with a guinea pig is that it can be varying temperatures of cold and a guinea pig will still drink it. It could be ice cold and they would deal with it.
As long as cold fresh water is available for your guinea pig to drink they will be happy.
