Quoted:
One of my cats always does this little ground-scratching ritual before he'll drink from a bowl. When he gets all wacked up on catnip, he smacks the bowl around and steps in it and moves it around. Maybe your cat does some combination of the two, or maybe he's trying to move the bowl. Refill his bowl and hang around near it 'till he goes for a drink, maybe he's just trying to get a better angle on it or something.
One of my wife's cats will drink from the bowl normally.
The other cat will scratch at the base of the bowl with both paws until finally drinking (both paws alternating pretty quickly).
Here's my theory OP: The cat is trying to make the surface of the water move so they can see it. Instead of making a move to drink and sticking their nose too far into the water, they'll make the surface ripple so they approach from the correct heighth.We bought a unspillable bowl from Wal-Mart. Got tired of the tupper ware container being flipped over by the dogs.
