i've had cats do that , one cat would knock the bowl with his paw to splash it before he drank. and also had one who would only drink from a faucet!!
the vet told me this was because some cats can't see the water in the bowl so they have to touch it or have it moving so they can see it to drink it.
My cats were always trying to move the water in their bowl and it would end up that they would push the bowl all over the room spilling most of the water out. I recently got one of those fresh flow water fountains that creates a stream so the water moves. They don't bat at the water anymore and they certainly can't move it around because it's too heavy.
Stephen eats this way! She picks up pieces of food with her paw and eats out of it!
Hehe what a little raccoon! My little Sugar does this too sometimes its funny! Mostly she likes to play soccer with her food and then eat it. My cats don't bat at the water Thank Goodness b/c I'm not home most of the time to clean it up if they did. The only time the water is knocked about is when my cats are chasing one another and bump the water.
