A recently released report from the University of Nebraska Extension, called "Feral Cats and Their Management," actually endorses catching feral cats in barbaric traps, and also whipping out a gun to shoot unwanted cats.
I concede that feral cats are problem, and this is an issue I've written a great deal about this past year. We don't know how many feral cats are out there, but we do know cats are America's No. 1 pet, with nearly 90 million pet cats (according to American Pet Products Assn.). It's estimated there may be up to 1 ½ times that number of un-owned cats, including both feral cats and strays. These cats typically live in colonies in urban alleys, or roam from farm to farm. They live on empty urban properties, on grassy areas of college campuses and in city parks — pretty much everywhere.
This isn't a new problem, or an issue unique to America. Many nations have been dealing with feral cats for centuries.
