Milk is for babies.
-Ahnold
No other creature drinks the milk of another animal, and even then, mammal babies generally get weaned. (well, except cats)
Sure they do. You put down a bowl of cow milk and every other mammal and a few non-mammals (snakes and such) will drink it.
Do animals domesticate other animals for their milk? Different story. Of course they don't. They don't plant and grow food, cook food or wear clothing either. You going to give up that too?
This is a pretty dumb statement. Bowls of cow milk, via jugs of cow milk, are not readily available in the animal kingdom.
However, if you put a bowl of milk out on the side of the street, every dog and cat in the neighborhood would fight over it. Put in a baby bottle...and apes drink it. Put it in a trof...and elephants would drink it.
No...I really don't see many animals in the wild turning down a free drink. They don't look at it and say to themselves: Hmmm...that is milk from another animal. I ain't drinking that.
They do what I do. YUM ;-P
