My Jade used to do that when I had my 250 liters tank - she would ONLY drink from the tank, and Bownie would balance on the edge of it. It wasn't covered as I had baby snapping turtles, but THAT fun ended when the turtles started showing a little too much interest in the cats'faces when they drank.

(Those things attacked and killed everything...my angel fish, my frogs...eachother)


Remember, Kirsten? *sigh*
