Cats – Cuddly Pets Indoors, a Threat to Birds, Wildlife, Health Outdoors



Cat lovers in the U.S. own about 90 million cats, bringing much joy to tens of millions of families.  There are also, however, an estimated 60-90 million unowned free-ranging cats in the U.S., cats which may be hit by vehicles, preyed upon by other animals, and can contract – and spread – a variety of diseases.  Global impacts of cat predation are documented: a minimum of 33 extinctions and a decline of at least 142 species of birds, reptiles, and mammals; mortality of an estimated average of 2.4 billion birds (~69% from unowned cats), 12.3 billion mammals, and hundreds of millions of reptiles and amphibians. Cats can also pose a threat to public health from potential transmission of diseases, most significantly Toxoplasmosis.  Attend this EPN breakfast program to learn more about these issues and perhaps more importantly, what people can do to ensure cats are well cared for and what can be done to reduce wildlife and health impacts of unowned and outdoor cats.

Cat Wars

Cat Wars: The Devastating Consequences of a Deadly Killer (2016, Princeton University Press) paints a revealing picture of a complex global problem—and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.
