All my cats do this, and they all have totally perfect vision. Cats don't have great depth perception at close distances, so it's actually quite normal for them to test where the water level is with their paws first before drinking. However, if this is a new thing with Tiger it might not be a bad idea to mention it to the vet the next time he's in for a check-up.
