Cats: fastidious drinkers

Cf. Science magazine online. They do not waste water on their fur.

They found that, as opposed to dogs, cats rest the tips of their tongues on the liquid's surface without penetrating it. The water sticks to the cat's tongue and is pulled upward as the cat draws its tongue into its mouth. When the cat closes its mouth, it breaks the liquid column but still keeps its chin and whiskers dry.


They realized that feline lapping balances the liquid's inertia, its tendency to keep moving upward as the cat draws its tongue in, against the pull of gravity, which drags the liquid back down into the bowl. To get a satisfying drink, the cat must lap faster than gravity can overtake inertia.
Lions and tigers also pull this off.
