A new analysis reviewed 109 studies comparing two approaches to managing free-roaming dogs and cats in developing countries: killing animals versus sterilization-and-release programs.
The review found that long-term birth-control programs were consistently more effective at reducing animal populations, lowering rabies incidence, decreasing “shelter” intake and kill rates, improving animal welfare, and generating positive public attitudes. In the developing world, the choice between neutering or killing is a no-brainer: animals are better off alive than dead.
These findings mirror those in the U.S., with one crucial difference. In the U.S., the choice between leaving dogs on the street and rounding them up to kill them is a false one. The same is true for cats. Open admission No Kill Equation communities are achieving 98%-99% placement rates. As such, dogs and socialized cats should be placed into homes, while unsocialized feral cats should be sterilized and returned to their habitats.
