Cats need fresh, pure water all day long. But you obviously can't keep refilling kitty's bowl while you're away at work all the day. The Fresh Flow purifying pet fountain not only continues to refill cool water to a constant level, it also automatically filters out contaminants by pumping the water through a replaceable charcoal filter. All you have to do is fill the fountain's transparent reservoir and plug it into the nearest outlet (the plug is removable).

Also, according to the manufacturers, the fountain's sloped water ramp design eliminates water splash to minimize the mess. This is also a great idea for cats who really prefer to drink running water, since you can't leave the faucet open all day, either.
