Grandpa Moses and His Cat, or The Cat Who Knew Where to Go

Grandpa Moses was many faceted in his interaction with the world.  He loved people, he was fearless, and he loved animals.  He had a pet canary (more on that later) and a pet black cat.  He trained his cat well.  Whenever the cat had to pee or poop, it trotted over to the bathroom, hopped onto the toilet, did whatever it had to do, ran over to Grandpa Moses, miaowed and made Grandpa Moses follow to the bathroom and flush the toilet. What a cat!  What a Grandpa!
