For those who have a Rogue/Kittypet/etc with plans of joining a certain Clan, please refer to this topic to clear up any potential confusion you might have. This also keeps anybody from spamming a Leader with questions about Clan-hopping
RIVERCLAN (Perchstar) ;; Rogues/Loners/Kittypets generally not accepted, except in extenuating circumstances. Clan-hopping cats are considered on a case-by-case basis. Exiled Clan cats are never accepted. Kits will be returned to wherever they wandered from. In circumstances where parents or origin cannot be found, they will be sheltered temporarily until apprentice age, when they will choose whether to stay in RiverClan or go elsewhere.
THUNDERCLAN (Acornstar) ;; Kits will no clear origins will be taken in, otherwise an attempt to return them will be made. Rogues, loners, and kittypets are accepted on a case-by-case basis with older cats receiving more scrutiny. Cats from other Clans may be accepted, but only after a conversation with the other Clan's leader to fully understand all sides of the reason why.
WINDCLAN (Tigerstar) ;; Kits are always accepted, but an attempt to return them to their kin will be made before allowing them to permanently reside within Windclan. Rogues, Loners, and Kittypets are accepted on a case-by-case basis, and if they are accepted, will be assigned a mentor and remain at apprentice rank until it can be determined by the Higher Ranks that they are trustworthy and accepting of Windclan's ways. Cats from other clans are accepted on a case-by-case basis depending on the reasoning for leaving their clan. A meeting will be had between Tigerstar and the leader of the cat's clan of origin.
SHADOWCLAN (Leopardstar) ;; Kits are always accepted, though an effort will be made to find their kin. Rogues, loners, and kittypets that show interest in joining ShadowClan will be offered a trial apprenticeship. Clan-hopping cats are examined on a case-by-case basis, and will generally require a conversation with the other Clan's leader. Exiled Clan cats will be expected to make a case for themselves and explain their situation on a case-by-case basis. Cats who join ShadowClan as apprentices or warriors will only be accepted as full members of the Clan once two ShadowClan cats vouch for their having adjusted to life in the marsh.
SKYCLAN (Wolfstar) ;; Kits are always accepted, though attempts will be made to return them to their original home. Rogues, loners, and kittypets are examined under a case-by-case basis, and will be required to complete at least two moons of apprentice training before taking a warrior name. Clan-hoppers and exiled Clan cats are examined under a case-by-case basis, and will have to prove their loyalty through a trial of Wolfstar's choosing before being fully accepted. Exiled Clan cats may never receive full warrior status depending on the nature of the exile.
