A name changing ceremony is a ceremony that takes place when a Clan Leader decides to give a Clan cat a new name. This is usually done when the cat's old name does not suit him / her anymore, generally because of an injury.
The leader calls a Clan Meeting, and performs the change with the following words: "Spirits of SpiritClan, you know every cat by name. I ask you now to take away the name from the cat you see before you, for it no longer stands for what he/she is. By my authority as clan leader, and with the approval of our warrior ancestors, I give this cat a new name. From this moment on he/she will be known as (new name), for (description of the reason)".
