Registration is a general term for a ceremonial acknowledgment by which an animal-role participant — Pet, Pup, Pony or other — is formally recognised as belonging to a Pack, Stable, House or event. Registration often accompanies a Collaring or the giving of a distinguishing mark.

The term reflects the influence of real-world animal registration traditions on animal-role ceremony.

Registration practices vary between communities. Some treat it as a solemn formality; others as a light welcome.
