Clan hierarchy starts with a kit. Once the kit reaches six moons of age they either become an apprentice or a medicine cat apprentice. When the kit becomes a medicine cat apprentice he/she will then become a medicine cat and will either be that for the rest of their life, or retire as an elder. Medicine cats do not usually become warriors later in life, the only example of this is Leafpool. If the kit becomes an apprentice then they will train to be a warrior. Once the apprentice is a warrior, they can become a mentor to other apprentices, a queen and raise kits, or retire as an elder. Some warriors become deputy, the assistant to the leader, and some deputies even become leader. Warriors usually don't become medicine cats later, the only examples of this are Yellowfang, Hawkheart,  Mudfur and Spottedleaf. Female leaders and deputies usually don't have kits because of her duties but it is not against the warrior code. Some of the male deputies and leaders sometimes father kits. Medicine cats cannot become queens or father kits, though there are some cases of this happening (Leafpool and Yellowfang). There is nothing in the warrior code about elders and apprentices not being allowed to have mates or kits but they generally do not. Some apprentices decide who their mate is as apprentices or have crushes on other cats as apprentices. Some elders are mates and retire at the same time and remain mates but do not have anymore kits.

Leader
The leader is the head of the clan. They have nine lives that were granted from StarClan. Their name always has the suffix -star. The leader is in charge of the clan, preforms naming ceremonies, appoints deputies, and speaks at gatherings. They decide whether or not to go into battle. They can mentor apprentices or have kits but don't usually due to their jobs.

Deputy
The deputy is the second in command of the clan. They must've had at least one apprentice before they can become deputy. The deputy may become the next leader when the leader dies. When a deputy dies or retires the new deputy must be appointed before moon high. A deputy is chosen out of warriors. An elder, apprentice, medicine cat or queen can't be deputy.

Medicine cat
The medicine cat heals the sick and injured cats in his/her clan. They also read prophecies, signs, omens, and dreams from StarClan. They go to the Moonpool or Moonstone or Whispering Cave every half moon to share tongues with their warrior ancestors. Medicine cats are not aloud to take mates or have kits. There is usually only one medicine cat but sometimes there is more then one. All medicine cats remain united past clan borders.

Warrior
The warriors of the clan are where most cats rank. They hunt and fight for the clans. They also do border patrols. They take mates and have kits. They also train other apprentices to become warriors. When a warrior dies the entire clans sits vigil for them overnight to honor them. When an apprentice becomes a warrior they keep a silent vigil all night and guard the camp that night.

Apprentice
The apprentices train to be warriors. They get a warrior as a mentor to teach them how to hunt and fight until they are ready to become a warrior. Apprentices must be at least six moons old. Apprentices are in charage of bringing moss back to camp, clearing out the nests in the nursery and elders den, and they check the elders for ticks. Some apprentices become apprentices late due to ijury, illness, or size.

Medicine Cat Apprentice
Once a Kit is six moons old they can become a Medicine Cat Apprentice instead of a normal Apprentice if they are accepted by the Clan Leader and Medicine Cat. The current Medicine Cat becomes their mentor and teaches them the skills of herbs and interpreting signs from StarClan. Medicine Cat Apprentices do not train like normal Apprentices, however they do learn basic fighting skills in order to allow them to defend themselves if ever caught in a fight.

Queen
The queens are the cats that raise kits. They can only be warriors, medicine cats, cnnot have kits. A cat can be a queen when they are expecting kits or nursing kits. Some she-cats don't go into the nursery until their kits are almost here. Some queens don't stay in the nursery with their kits. On rare occasions a she-cat stays in the nursery when she isn't nursing or expecting kits but doesn't want to retire.

Elders
Elders are retired deputies, medicine cats, warriors, and queens. They retire when they feel that they are too old, or are injured in a way that prevents them from continuing what they used to do like, going deaf or blind. Some elders fight when the clan is invaded, other protect kits. They are checked for ticks by apprentices and their bedding is taken care of also by apprentices.

In WindClan they also had two different Clan roles. Although both were still considered Warriors, they hunted and fought differently. These were Tunnellers and Moor Runners, this began when one of WindClans ancestors Shattered Ice first attempted to use tunnels, however much later the role of tunnellers was taken away by Heatherstar, who deemed the tunnels too dangerous.

Tunnellers: Tunnellers dug tunnels underneath WindClan territory. this made it easier to hunt rabbits in leafbare and also gave them an edge while fighting, as well as an escape route if they needed it.

Moor Runners: Moor Runners ran aboveground, marking the boarders and hunting rabbits across the moor.

StoneTeller: The StoneTeller (The Teller Of The Pointed Stones), also known as the Healer bares most of the responsibility for the Tribe. They are equivalent to both the Leader and the Medicine Cat of a Clan. They lead the clan, heal the clan and interpret signs from their warrior ancestors, Tribe Of Endless Hunting. The StoneTeller also has not got the support of a Deputy.

Kit: a Kit is a new born cat, until they are old enough to become a To-Be they will remain in the cave with their mother.

To-Be: Once a Kit is eight moons old (8 months) they become a To-Be. A To-Be is a cat who is being trained to become either a Prey Hunter or a Cave Guard.

Prey Hunter: A Prey Hunter is a cat who is purely responsible for catching Prey for the Tribe.

Cave Guard: A Cave Guard is a cat who must protect their tribemates, they escort the Prey Hunters to protect them from predators and protect the cave they live in from any threat.

Kit-Mother: A Kit-Mother is the same as a Queen, a she-cat nursing or expecting Kits.

Elder: An Elder is a cat who is too old to be a Prey-Hunter or Cave Guard any longer.

Council: Exclusive to MemoryClan, the Council is a group of cats originally elected by the Clan to lead them. They are not granted nine lives by StarClan, but are the guiding force behind the Clan, as a leader is. New members are elected by the current Council Members, and require a 2/3 majority.
