Most Ninneko live in a castle located in the district of heaven and do not possess affiliation with any country or shinobi villages, though a few have been shown to wear a headband with the kanji for written across it, like all the hidden villages have. They protect, and roam the corridors of the Fortress and intercept any threats.

Abilities
Unlike most animals, Ninneko are capable of performing techniques. Despite this they are incapable of performing Hand Seals. Ninneko have also demonstrated the ability to use Chakra Flow through their claws, making them the only animal species to use the skill.
