Tribal Cat Ranks:
Healer(Stoneteller):
The Tribe's Healer is basically the same thing as a Clan's medicine cat and leader put together. Not only does the healer lead the Tribe, they also use healing herbs to cure wounds and sickness. The Healer receives signs from their warrior ancestors in the Cave of Pointed Stones. They interpret the signs of rock, leaf, and water to read messages from the Tribe of Endless Hunting.
Unlike Clan cats, Healers do not dream. The Healer doesn't have nine lives and it's easier for them to be killed. The new Healer is appointed by the previous Healer
Prey-Hunter:
Prey-hunters are the lithe, quick cats of the Tribe who can jump high to catch mountain birds such as eagles or hawks to feed to their tribemates. Prey-hunters are tribe cats whose only duties are to catch prey for the tribe. They are the hunters of the Tribe, using stealth and surprise along with camouflage to catch their food. It is their responsibility to feed the Tribe and catch their prey, especially for the nursing cats, and the young and old.
They depend on speed, for there are not many places to hide in the almost-bare surroundings, like WindClan. Normally prey-hunters hunt in teams to help catch prey.
Cave-Guards:
Cave-guards are thick, strong, and lean cats that protect and guard the entrance of the tribe's cave.
They are the main fighting force of the Tribe and have the responsibility of defending the cave from predators such as big birds. Watching the skies to protect the prey-hunters from hawks and eagles while they hunt is another one of their responsibilities. They are also the most experienced with fighting
To-Bes:
The equivalent of an apprentice,
to-bes are young cats in training. To-bes are trained in either prey-hunting or cave-guarding. They train with their mentors and learn the skills of what they have to learn. When they are finished training, they are made into either prey-hunters or cave-guards by the tribe Healer. Tribe cats believe that they are born into their duty, though they can change positions. Unlike Clan apprentices, to-bes start training at the age of eight moons.
The Stoneteller will receive a message from The Tribe of Endless Hunting when it is time to choose his own to-be.
Kit-mothers:
As their name suggests, kit-mothers are she-cats who are about to have or are nursing kits, the equivalent of queens. A prey-hunter or a cave-guard becomes a kit-mother when they become heavily pregnant and they can't continue with their duties.
Kits:
Kits are young cats that are not yet to-bes; the same as Clan kits. They are too young to do to-be duties, so they stay in the nursery with their mother.
Kits stay a kit for 8 moons. At their birth, it is foretold by the Tribe healer if they will become a prey-hunter, a cave-guard or the next Teller of the Pointed Stones. Kits that seem fast and lithe are prey-hunters; kits that look strong will be cave-guards. They can be to-bes when they are eight moons old.
Elders:
Elders are the oldest and weakest cats in the Tribe. Elders are retired cats that have stopped doing their Prey-Hunter or Cave-Guard duties. They are often consulted in difficult times. The elders of the Tribe have a very similar role to the elders of the Clans. They are fed by the Prey-Hunters and are protected by the Cave-Guards
