The Fluffball Universe

"The Fluffball Universe" is the name given to the canon created by Cameron Costin Clevenger Stephens in his stories about the character Fluffball T. Gato.

PREMISE
At some point in the 22nd century, humans engaged in an atomic war that obliterated much of the life living on Earth, including the human beings themselves. Some animals survived the mass extinction however, the most notable being domestic cats. Roughly seven hundred years pass with little to no development, the remaining species repopulate the planet.

Meanwhile, a parallel version of Earth --one that developed drastically differently from our dimension following the K/T extinction event -- suffers from a massive resource crisis. This planet, which contains hyper-intelligent creatures that had evolved from cats (named the "Kchll") and another highly intelligent species with an unknown origin, but vaguely resembling a dog/rabbit hybrid (named the "Rufph") is on the verge of a complete industrial meltdown. In order to mend the crisis, a Kchll named "Sash" and a Rufph named "Rufphbol" make plans to create an inter-dimensional ship out of a fluorite crystal in order to access a parallel Earth that they can subsequently harvest for resources.

The ship is successful in leaving their home dimension, but the ship tears a hole when traversing the inter-dimensional plane, and both Sash, Rufphbol, and all their equipment is irradiated with something only referred to as "the transdimensionals," which renders both beings immortal, but severely damages their minds.

Upon crash landing in "our" dimension, Sash, realizing that their homeworld is almost certainly doomed and suffering the effects of the radiation, loses his mind. At some point after they were stranded, he impregnated a tabby cat (which was possible due to their parallel DNA) and committed suicide with a blade that had been irradiated by the transdimensionals, as only other irradiated objects were capable of killing him.

The impregnated tabby cat eventually gave birth to a litter of kittens, who were then consequently raised by Rufphbol. He names the runt of the litter "Flufphbol" after himself, but as the kitten grew up, he simply referred to himself as "Fluffball," and his guardian as "Ruffball."
