You might be thinking they feast on snow. Eating snow to obtain water is 
metabolically expensive–it would take too much energy to melt down enough 
snow. Consequently, polar bears have evolved so that they don’t need to 
drink free water.
Polar bears get their water from the chemical reaction that breaks down fat. 
This is why a polar bear’s diet is high in fat but low in protein. For 
example, when they hunt seals, polar bears will eat the blubber, but leave 
the rest behind for scavengers. The so necessary salt for this reaction is 
taken from the few sips of sea water.
