Collars with tags are commonly used for pet identification. The tags contain updated contact information of its owners. Collars and tags provide a form of visual identification for cats and are often alternatives or used in addition to microchipping. 

If a cat is run over by a vehicle and killed, the body may not be checked for a microchip but information in the collar will help find the owners of the cat so that they will stop searching for their feline pet.

There are usually risks involved when your cat wears a collar. Being active and inquisitive creatures, they are often enticed into small or dangerous nooks and crannies, and can get caught up by its collar on a fence or a branch, and could potentially choke or get injured. A cat can also get his leg through the collar especially when it’s too lose, causing injury to the front leg which can be potentially serious without prompt medical attention.
