Tuxluver .....does that sound familiar! My almost year old M .Coon practily takes a bath in his water dish!
His name is Wylie (aka 'the waterboy'), and he does the food thing too- eats with his paw, and also likes to put his food into his water (now THAT is a mess!)
We have tried a really heavy dish, placemats, plastic cafeteria tray, and finally putting his water dish into a deep plastic dishpan. Nothing has worked- maybe we will give the nailing it to a board thing.

I am hoping he will outgrow it.........
