This unusual comic book recounts a true story that happened on a small island just off the coast of New Zealand in 1894. The tragicomic hero of the tale is a cat named Tibbles, who belonged to the keeper of the island’s lighthouse.

Tibbles discovers a rare species of previously undescribed flightless bird – the Stephens Island wren, and simultaneously becomes the cause of its demise, thereby inadvertently contributing to global awareness of the danger of domesticating non-native animal species on other continents.
