The Global Republic of the Cats (GRC) is a nation formed in 2029 after a series of events which changed the behavior and intelligence of all domestic cats in the world, making them start to flee their houses or places of standing and unite as a global people with its own languange and customs. They began to settle colonies in the Antarctic peninsula and later invade the entire Antarctic continent, establishing there the first non-human nation in Earth's history. Due to the close presence of cats through human history, cats learned all human sciences and arts when they became sentient and quickly formed an advanced civilization comparable to the human potencies of the late 2020s.
