Kchll (fictional species)

The Kchll (sometimes simply Kll), were a race of sentient beings on a parallel planet Earth. Their DNA mirrored that of many domestic cats, except this species was bipedal and significantly larger (approximately five feet tall). When a Kchll named "Sash" became stranded in our dimension, he began suffering from insanity and impregnated a domestic cat. One of their children was Fluffball Gato, the main character of the "Fluffball Universe."

Fluffball Gato is half Kchll and half domestic cat: they were able to interbreed due to being the same species from alternate dimensions. However, the resulting hybrids looked neither like the Kchll or domestic cats, instead having disproportionate heads and cat-sized, bipedal bodies.
