It's official.. I have, in fact, seen it all and can die a happy woman. Don't have a patch of grass for your pup to pee on? Well, you do now! Hook your patch of synthetic grass up to a hose, and the automated hose timer will turn on the sprinkler head to wash all your pup's urine away. Sorry, it doesn't clean poo. $279.00 at PorchPotty.com.
