Q: I was truly dismayed reading your article in the Albuquerque Journal last Sunday. Feral cats are well known to be a major threat to small birds. The numbers of wild birds have dropped in America since researchers began counting in 1970. Some estimates are 30%.

If someone had a pet lion or tiger and let it roam the neighborhood hunting children, would that be acceptable? Of course not. You may not want to admit it, but feral cats are an invasive exotic species, just like the cheatgrass, salt cedar and tumbleweed. You telling people to respect their freedom-loving pets and help them spend all of their time outdoors killing whatever they can overpower is not helpful.
