I think this is a typo. Doesn't it have to be "sweat"?
3-3)There are many reasons why cats spend so much time licking themselves...In cold weather, repeated licking smooths down the fur and keeps keeps body heat in. During hotter days, cats may lick their fur to cool themselves. It's much like how we feel cool when sweet dries on our skin....
You are right.
