Solve the problem of identification, and a giant step is taken toward, if not solving, then substantially ameliorating, the surplus dog and cat problem. Once public authorities know who is getting rid of an animal, that person can be severely (repeat: severely!) penalized. At minimum, one consequence will be at least to dissuade, and at most bar, irresponsible termination of the human-companion animal relationship (i.e. dumping animals rather than surrendering them).
