Name changing ceremony

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. For example, when Sparrowpelt lost half of his tail, he was re-named Halftail.

Procedure
The leader calls a Clan Meeting, and performs the change with the following words: "Spirits of StarClan, 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)".

Cats who Have Changed Their Names in the Warriors Series
It is likely that Crookedjaw, Deadfoot and Tornear are also results of name changes, as they refer to injuries obviously recieved after birth. However, their previous names are not known.
