My Gump is blue eyed, and he is the only one of my cats who always paws at the water dish...whether there is a little bit or a full dish, he will paw at it and pull it across the room...
My husband wondered if it is because of his blue eyes, he may not see as well and not be able to tell where the water is unless he moves the dish to see the ripples in it...
I have also tried the water fountain type of dishes...he plays with that also...
Maybe he is just one who likes to play in water...but I always have a puddle of water on the kitchen floor and a dry water dish to deal with...
edit added: I got to searching the itnernet and found this statement
another edit, just because I kept searching and found this, which I thought was cute...will have to pay more attention to my cats!The blue eyes of Siamese cats are not a sure sign of deafness, but instead are associated with poor 3-dimensional vision

Cats "Kiss" with their Eyes. Have you ever noticed your cat gazing at you for a long moment and then slowly blinking his eyes? That's the kitty equivalent of a kiss, and you should feel very flattered. Of course, a nip on the nose is also their way of giving a kiss. If you want to show your cat you love him, give him a kitty kiss right back. No, not on the nose. Just give him that long stare and slow blink and see what happens.
