The Kitten Kingdom is a prominent civilization featured in the Epic Battle Fantasy games. As its name suggests, it is a nation inhabited entirely by cats. Its current size is unknown, but it was once the dominant civilization on the planet due to the influence of Godcat.

The game begins in the Kitten Kingdom, although the scenery is drastically different from the ruins displayed in later installments. Following the events of EBF1, Matt and Natz are recovered by the residents of the Kingdom and brought back to recuperate. Upon hearing of Lance's conquest of the planet, Matt and Natz go to stop him. For unknown reasons, this entails slaughtering a number of Kittens to "escape" the Kitten Kingdom, although it was explicitly stated through dialogue that the Kittens were friendly.
Epic Battle Fantasy 3
The Kitten Kingdom Ruins comprise the third-to-last area in the game, and appears in stark contrast to the sunny, garden-like environment of EBF2's Kitten Kingdom. The Ruins are surrounded by desert, and house a number of Native American-like NPCs who express their thoughts on shooting the archeologists that came to inspect the Ruins.
Epic Battle Fantasy 4
The Kitten Kingdom Ruins appear yet again, this time serving as the stage for the final battle between the party and the Godcats. The Kitten's history and culture are explained in much further detail here, revealing that Kittens were intended to be the dominant race on Earth rather than humans, who were created to be slaves to the Kittens. Ancient humans worshipped cats as gods before an uprising of ambiguous origin drove the Kittens out of power, causing Godcat to be disappointed and curse the Kittens to lose their limbs (therefore explaining why Kittens are drawn in-game without arms nor legs). Godcat was also sealed by the crystals so that it couldn't descend from the heavens and rain fire and brimstone upon the infidels who dared challenge it. Before this happened, the Destroyer side of Godcat created Akron in order to punish the humans. Fortunately for the humans, this plan was thwarted when the party slew Akron in the final boss fight at the end of EBF3.
