Felis sapiens

Felis Sapiens are a strange humanoid life form who evolved from a man's cat.

Physiology
In terms of appearance, felis sapiens seem to resemble humans. However they are still known to have many common habits of cats, such as obsessions with sleeping and eating.

Origins
At some point in an unidentified century, a man named Dave Lister was serving aboard the mining starship Red Dwarf. He was caught smuggling his pregnant cat aboard, and consequently sentenced to 18 months in stasis. Unfortunately, during that time, there was a radiation leak that resulted in the deaths of every save Lister and the cat, who was safely sealed in the cargo hold when she gave birth.

Evolution
Somehow over time the species continued to reproduce and evolve. They developed a mythology centered around "Cloister the Stupid" (Lister), a civilization, and even their own style of writing based on different smells. It was believed that when a cat died, they would travel to a place called Fuchal (originating from Lister's plans to move to Fiji) where they would open a temple of food.

However, at some point, a the people began to dispute on the colour of the hats that would be worn by those who worked in the temple of food, and a holy war broke out between the faction that believed that hats should be red, and the the faction that believed they should be blue (they were actually supposed to be green). In the end they called a truce and set out to find Fuchal. The faction that believed the hats should be blue followed what they believed to be holy text (actually a laundry list) and crashed into an asteroid. The fate of the other faction is unknown, though it is possible that they eventually colonized another world.

Only a handful of Felis Sapiens remained behind, and gradually they all died out until only one was left, at which point Lister finally woke from suspended animation.
