> Like gee I wonder why they want to drink cool delicious clean water from a tap, not dank stagnant water from puddles. What a mystery for the ages!

I mean, it could also not be about taste at all, I'm sure not all animals taste things the same, not even all humans have the same taste it seems, I can't stand fish and I love licorice, many are the opposite :)

Besides, many animals seem to enjoy just "different" things. When I'm out and about with my dogs, they love trying to drink water from puddles, even if I have a portable bowl with fresh water right next to it. Maybe it's more "interesting" or "flavorful"? Who knows...
