Cat Water

We give our cats fresh filtered water twice a day.  When it's time to fill their water bowl, there is always a little water left. Instead of pouring this filtered water down the drain, I pour the water into a second bowl in a different location. Our cats will drink the second bowl dry! This "reuse" of water reduces our water filter use. Thanks, cats, for your help reducing waste! :*

P.S.  Can you tell me where to recycle my water filters?
