Echo Location

Those who know me, know that I have been living with a unique black cat since 1991. Mischief was appropriately named and has been a source of entertainment throughout the years. As he ages, I've noticed that his hearing is not what it use to be (and yes I tested him to ensure it wasn't selective hearing) and his sight is not as good as it once was. Over the past couple of years he has developed a new routine. Each time he approaches the water bowl for a drink, he seems to use some form of echo location to determine the water level of the bowl .
