Warm milk is great for helping humans get to sleep and is a pretty popular drink all round.
So can guinea pigs drink warm milk and if so how much of it can they drink?
Unfortunately, guinea pigs can’t drink warm milk at all. This is because they cannot eat or drink anything that has been warmed up or or heated in anyway. They are herbivores and their stomachs just can’t handle it.
So warm milk really is something to steer clear of as far as guinea pigs are concerned.
