Licensing is all part of our rabies vaccination law. You get the rabies shot, a paper certificate (license) and the rabies I.D. tag. The vaccine is good for 3 years, but our state law requires they be updated yearly. My vet now just re-issues the license part for a reduced fee yearly. That way your pet doesn't have too many vaccines so close together. If everyone would actually put the tags on their pets' collars, then the theory of reuniting them when lost would work. Other than that, only a microchip will work.

Some of my cats will keep their collars (with tags) on, but others always find a way to get them off. I use the break-away collars though because it's not worth risking strangulation for them to wear a collar indoors!!!
