The Old City of San Juan once had a problem with rats. The solution was cats... until the cat population got out of hand. Some people advocated capturing and killing the cats, but a group of volunteers lobbied for permission to trap, neuter, and vaccinate the cats instead. This group has successfully done so with 95% of the feline population and, in addition, have set up feeding stations along the path beside the walls of San Juan. While ambling along this beautiful pathway overlooking the ocean, visitors can see the cats - and the iguanas - of San Juan. Here are just a few of the cats who've been rescued by Save A Gato.
