Character one from my new project, Purrgatory (I know, but it was too tacky to pass up!)

These are cats who live in a halfway house between heaven and hell. Their job is to clean up and harvest the dead, and they get all their sustenance from the bodies they clear up. Each cat is responsible for clearing up one part of the body. The cats themselves cannot leave purgatory, and are stuck there for infinity. None of the cats are capable of human grade speech, they simply yowl, scream, hiss and screech at one another.
The project is very much in its infancy, so I'll add more once I've got my head around it.

This is Tibia.
She is quite an old character, based originally on my Sphynx avatar from secondlife (from mutation industries). But over time she evolved into a different character, and inspired me to create a whole world of undead cat beasties. I suppose technically they're more kinda were-cat/zombie/monster things than pure cats.
Tibia is somewhat manic, particularly when she's found new bones. She tends to giggle inanely, and is rather childish and mischievous.

Skull reffed from Google.

Tibia and Purrgatory idea ish mine :)
