Every cat should have an ID tag.
Regardless of whether your cat is indoors only, indoors and outdoors or outdoors only when supervised, he or she should have an identification tag. Cats that are even indoors only can get out. This can occur if someone leaves the door open or in the case of a tragedy such as a house fire or burglary. If your cat gets out or lost, an ID tag will be the best method to be reunited with your cat.
When getting a tag, make sure the letters are permanent and ensure that the information on the tag is current. Consider using your cell phone if it is your primary phone number. .
