For a few generations, humans have been monitored by the government. They must wear an ID chip in their neck that agents and catbots will scan. They also must update their ID chip once a year in a special ID office where they are questioned. They cannot have a job or study, the government provides them food and shelter. Pure blood humans have their fertility regulated when they reach adult age.

The Kitty-only government has taken over the world. They are exclusively made of cat-persons with high feline features and genetics. They removed humans from positions of leadership in government and business. Slowly but surely, they also privileged those who have more cat genes and features, making humans lives harder and harder. Their final goal is the total extinction of pure human genetics. Kitty-Only government is nowadays ruled by Lucifur, a female Kitty with very high feline genetics. They rule the whole world as a single united country, ending all human wars and conflicts since the take over.

The government's flag is yellow with red cat-like pawprints on it, symbolizing the long and hard march of the cats taking over the world.

The dolls are Kittys with high feline features that had been genetically engeneered and bred for various purposes when humans were still leading the world. Porcelain-dolls were bred for their beauty and are unable to live by themselves, they don't have claws or fangs and don't have high intelligence. War-dolls were bred for their agility, speed and focus, have sharp claws and fangs, high intelligence. Guardian-dolls were bred for company and safety and have average claws and fangs and average intelligence.

Centuries ago, a whimsical but rich man decided to bring his catgirl fantasy to life. He hired scientists to mix feline and human genetics to create what would be the first real catgirl ever. Others asked to have their own, and more were created, as well as catboys. Since then, some were released and freed, others with more cat features were created for various purposes and named dolls, and the frontiers between them and humans became blurred. Pure humans are rare nowadays and seen as a flaw. The ones that have the most cat genetics and features are called Kittys.

First, cats became pets for humans. Then, they were indispensable companions. They became loved, and were the icons of cuteness. Cats were appointed as station managers, as mayors, were all over the Internet. And the catgirls were the most common fantasy amongst male humans: girls with cat ears and tail. Slowly, unnoticed, they took the power over naive humans enjoying to be treated as slaves by their cat masters. Then the genetic miracle happened and catgirls became a reality. It was the start of the new era.

When genetic mixes of cats and humans were all over the world in every part of the society, Mittens, a grey male Kitty, proposed that in every country of the world a Kitty would present to rule the government. The stupid humans didn't realize the true meaning of all this and laughed, in the end one by one, every country had its Kitty governor. Once the first country was won, the humans of the others countries wanted to, also, have 'their' own Kitty governor. When every single country of the world was ruled by a Kitty, they removed all national borders, took over the full power and proclaimed that the world was now a single, united country under the lead of wise Mittens.

Kittys are the product of genetic engeneering and selection. They are the ones with the most cat genetics and features except for the dolls. Kittys are considered as a "natural" pure species by their allies. They have a humanoid body with a feline head, fur all over their body, and a feline tail. They have the intelligence of humans and can talk, but have the agility, flexibility, reflexes of cats. They can jump very high and have fangs and retractile claws. They usually consider themselves as superior to humans due to their enhanced abilities.

Lucifur is the actual leader of the world. She is a calico Kitty. When she was a kitten, her parents had been killed in an accident involving a family of humans that all survived, since then she hates humans and despises them. She sweared that she would spend her lifetime ensuring that no other life would be harmed by the meaningless, weak and stupid humans. She thinks that violence is necessary against humans since they would not understand anything else. Lucifur took the lead when the previous Leader suddenly died, making the place vacant. She was just there by accident in the office when someone came and saw her, that's how she became the ruler of the world.

Kittys love their Leaders and trust them entirely. The Leader stay in place until death or if they choose to pass the power, and the shift is always peaceful and a moment of joy and parties all around the world to thank the previous Leader and welcome the new one. The new Leader is usually chosen by the previous one, or just decides to take the job. When the previous suddenly died, the world was left without Leader for a few days. Lucifur walked in the office when she was trying to find her way out of the government building after paying her taxes. Someone saw her there and it was declared that she was the new Leader.
