Catch-and-release may be great for fishing, but many wildlife biologists, veterinarians, and environmentalists feel catching and releasing feral cats is a terrible idea.
Cats, not native to America, add an unnatural, lethal dimension of tooth and claw to the outdoors. The problem is convincing far-divorced-from-nature cat lovers that free-roaming cats are serious killers taking a staggering toll.
An estimated 80 million feral cats prowl the outdoors. Studies show that Wisconsin alone annually loses 17 million to 30 million songbirds to them. Minimally, feral and domestic cats annually kill 100 million to 300 million songbirds in America. Some estimates put the number closer to 1 billion.
