Thanks — sort of — for the disturbing Sept. 19 front-page article on small regional zoos [“Roadside dens of grim captivity”]. I have a hard enough time dealing with the way animals are raised and slaughtered in industrial nations. This reminder of what we do to the animals we want to keep alive is even worse because they have no escape but a slow, grim death from neglect, torment and depression. Such activity should be fiercely regulated or, better yet, banned.
