We know that guinea pigs can drink water and that it is the primary way that they get nourishment and quench their thirst.
Can guinea pigs drink warm water?
Cold water is the best type of water to be fed to them but what if the water is warm?

It depends how warm it is.
Obviously sometimes the sun is so hot that the water is naturally warm and they have to drink it.
However if it verging on scolding hot, then no.
I wouldn’t purposely give my guinea pigs warm water however it is slightly warm then that’s fine.
Anything more than that then it may harm their palettes as they are just not used to it.
