It may be a reference to Stray and Little Kitty, Big City, but there's no real explanation given as to why there are cats wandering around Cronos: The New Dawn and how they managed to survive The Change.
Listen for the meows of each cat above the noise of the Orphans' groans and cries. These feline friends not only intrigue the Warden, but they're here to keep the trophy hunters busy and your inventory full for conflict areas and boss fights.
