My characters - Larry and Skrich.
Larry is a cat who lived for fifteen years in a large mansion with a rich old lady. When she died, Larry stayed in the mansion all alone. He has several years of wandering around the house in the hope of finding someone alive, except mice, which he ate, until he finally went mad. At his age, it was easy. Larry was absolutely crazy to do different things, and once tried to scratch out his eyes, and that was the reason why he died.
Larry is a ghost now. In his dilapidated mansion sometimes wander curious tourists and children. Blind cat chases them, scaring almost to death :D
Raven Skrich it's the only one Larry's friend. Larry met him after he died. In fact, Skrich was originally interested in lots of sparkling things stored in the mansion, but once he started talking about something with Larry, and they became friends.

Sorry for my bad English :0
