Photograph by Jak WonderlyThe problem with outdoor catsCats have contributed to the extinction of 63 species of vertebrates, most of them birds, says Peter Marra, director of the Georgetown Environment Initiative. “The fact that they’ve caused these extinctions is bad enough…. [Additionally] we know that they have a significant impact on populations globally, whether they’re threatened or not,” he says.Marra, who was formerly the director of the Smithsonian’s Migratory Bird Center, is the author of Cat Wars: The Devastating Consequences of a Cuddly Killer, which details why cats can be dangerous to species diversity. Since the book’s release in 2016, not much has changed regarding outdoor cat regulation, Marra says, but there is a greater awareness and understanding of the issue.Some argue that cats are natural predators and should be allowed to roam and kill prey as they please. But, according to Piazza, the fight is not fair. This argument overlooks several important factors.In a natural predator-prey relationship, predators hunt until there isn’t enough prey in the population to feed them, she explains. As the predator population dwindles, the prey population has time to repopulate. Domesticated cats disrupt the cycle.2:35“They’re in the same area for 15 to 20 years, they’re fed by their humans, they don’t have to hunt to survive,” Piazza says. “They just constantly kill and nothing changes their population, so it doesn’t give local wild populations time to rebound as they would if it was a natural predator-prey cycle.”The outdoor cat debate is a polarizing issue, and Piazza says that the project isn’t meant to alienate animal lovers. Her goal, instead, is to unite them. She suggests keeping cats on leashes, having a catio (an enclosed outdoor patio for your cat), or pledging to make your next cat an indoor cat. Not only do these practices protect other animals, they keep cats safe and healthy, too.Related TopicsDOMESTIC CATWILDLIFE CONSERVATIONBIRDSYou May Also LikeANIMALSThe surprisingly fraught fight for a pet cat in AntarcticaANIMALSWhat is your cat telling you?

In the UK, during a five-month survey period, pet cats were estimated to have brought home 57 million mammals, 27 million birds and 5 million reptiles and amphibians—which implies that they killed several times these numbers. 39 Another study, using data from bird ringing programmes in France and Belgium to assess garden bird predation by , 1. In the United States, cats kill an estimated 1.3–4.0 billion birds each year. (Texas Biodiversity) Cats are the leading cause of death for birds in the United States. The second leading cause , For the USA, the death rate of birds per year has now reached 1.5 billion, equivalent to one-fifth of the entire global human population . To arrive at a relatively reliable total number of bird kills per cat, even in urban environments, one usually relies on surveys of cat-owning households., This is especially concerning because birds are already at risk across the world. North America alone has lost an astonishing 3 billion breeding birds in the last half-century, due to threats like climate change, predation by feral and pet cats, and the loss of grasslands and other habitats. This panzootic is only making an ongoing extinction , Cats kill between 1.4 billion and 3.7 billion birds and between 6.9 billion and 20.7 billion small mammals yearly, according to new research. featurepics.com Jan. 29, 2013, 4:11 PM EST By Science, .
