Ranks

Leaders are, naturally, the leaders of their groups. It is their duty to keep the peace, and, while more everyday tasks are usually entrusted to the deputy, it is their job to make major decisions that affect the group as a whole.
Deputies are the leader's second in command. They are the most powerful apart from the leader themselves, and are expected to step up as leader when their predecessor is deceased or otherwise no longer able to fulfil their duties. They are responsible for the organisation of patrols.

Medics are the healers of their groups. They are not so much spiritual leaders as practitioners of medicine, collecting and administering herbs for the health and wellbeing of the group. They are obligated to aid anyone in need of medical assistance, medics existing outside of the usual group loyalties.
Medic apprentices are the apprentices of the groups' medics. They will remain an apprentice a great deal longer than any of their warrior counterparts, for the training of a medic is far more extensive than that required to become a warrior. They may even be an apprentice long after they have received their medic name, until the death or retirement of their mentor.

Senior warriors are warriors with great experience. It is not unusual for the leader or deputy to call upon them for advice. They are seasoned warriors and should be treated with a certain degree of respect.
Warriors defend and feed the group, making up the majority of any group. They are trained in fighting and hunting, as well as various other techniques their group specialise in. They mentor apprentices to become the next warriors, passing down the knowledge that their own mentor taught them.

Apprentices are members of the group training to become warriors. They are usually between the ages of six and twelve months, though there are a few exceptions such as illness, injury and inexperience. They usually carry out the group's more tedious chores.
Kits and pups are cats and dogs under the age of six months. They are usually collectively referred to as children, and singularly, when the species of an individual is unknown, child. They are nursed until they are old enough to commence training, but, in the rare case that they do not have a parent able to nurse them, they will be nursed by a foster parent, or, if weaned, they will sleep alone.

Queens are members nursing children. Once their children are not dependent on their milk, they may choose to resume their duties, whatever they may be. Some parents, if unable to produce milk, never nurse their children at all, instead choosing another to nurse their children.
Elders are retired members of the group. They may be former warriors, deputies or leaders, even, or a member retired early due to an injury rendering them incapable of normal warrior duties. They are to be treated with utmost respect, and can be quick to take offence.
