Calisto the Faery Cat Creature

He was named Calisto when he was born but he actually answers to "Fiddle". Being a very curious fella, he was always sticking his nose places he shouldn't. He always heard his older lady say, "Don't Fiddle with this." Or, "Ooh Fiddle, it's broken now!" when he knocked something over. It was always "Don't fiddle with this, or fiddle with that, but he just started to think they changed his name. It just took them a lot longer to catch up. Now, they just call him "Fiddle" and tell others it's his middle name.
