There’s more than one way to spay a cat

Running a city can be an expensive business. There are potholes to fix, policemen and firefighters to fund, and mountains of refuse to collect. In many cases, the kitty is empty.Other sorts of kitties cause problems, too. Some 480m of the world’s 600m domesticated cats are thought to be free-roaming. Strays can be unsightly and can spread diseases, either to each other or to people. Many endure short and uncomfortable lives. Even those that land on their feet can cause suffering elsewhere—more than 60 species of animals, ranging from mice to birds, have been hunted to extinction by predatory cats.
