Domestic cats in the United States are beloved pets but they can also be a major threat to birds and other wildlife. After the domestic cat was introduced to the United States by European colonists, the number of domestic cats has skyrocketed in the past 40 years.
Today, more than 100 million feral and outdoor cats are loose in neighborhoods and wildlife habitats nationwide. There are so many of them that they are classified as an invasive species with extinction-level impacts. According to several studies, cats kill between 1.3–4 billion birds and 6.3–22.3 billion mammals in the U.S. per year; making them the largest human-influenced source of mortality for birds and mammals in the country.
Globally, domestic cats have caused the extinction of several mammals, reptiles, and at least 33 bird species.
One would think that people helping to reduce the population — humanely — by feeding, trapping, spaying and neutering as many cats as they can, that this would be a service to society and nature as a whole. Unfortunately for Beverly Roberts, 85, and Mary Alston, 61, one would be wrong.
Roberts and Alston were both found guilty of multiple criminal charges this week, fined, and sentenced to jail and probation, for carrying out this very service.
