Ailurocosm

Eons have passed since Earth fell to the menace of humanity. Due to the benevolence of a race of alien life-forms, some species from the doomed planet have been rescued... and modified. One species was given the gift of sentience, and the opportunity to prove that Terran biology is not predestined to self-destruct. This species is the Pseudofelis corvus: a combination of feline, avian, and alien DNA altered to conform to life on a new and unique planet.
