domesticated cats, our beloved household pets, are found throughout the world - but they are not a naturally occurring species in the wild. they first appeared in the united states and its territories during european settlement in the seventeenth century. although cats are often kept indoors, they sometimes escape or are released into the wild by their owners, ultimately contributing to a feral cat population through reproduction. feral cats may look like pet cats, but they are typically fearful of humans, and they may even scratch or bite if approached.
feral cats have significant impacts on natural environments. they eat billions of birds and small mammals in the united states every year and have been identified as the major contributor to reducing bird populations. globally, cats have been suspected in the extinction of several mammal, reptile, and bird species. feral cats can also spread diseases to humans, such as toxoplasmosis and rabies.
