cats and water

cats claim they don't like water except to drink, but one day i found my sister's cat, cc, playing in my bathroom sink. sometimes she plays on the edge of the bathtub between the curtains during shower time. she is an elusive creature; sometimes i don't see her all day. my cat sam wakes me up at 5:30 or so for water, treats and to open the sliding door. cc and dennis also appear after i get up so they can go out and hunt. after a treat and a drink though, sam goes back to bed until noon when he pesters me for his noon treat.
