Where House Cats Roam: Researchers Compare the Mysterious Wanderings of Pet and Stray Felines: Scientific American

Scientists at the University of Illinois and the Illinois Natural History Survey recently attached radio transmitters to the adjustable collars of 18 pet and 24 feral cats in southeastern Champaign-Urbana and tracked the animals by truck and on foot for more than one year. The research, published in the Journal of Wildlife Management, shows that pet cats maintain a rather lazy existence: they spent 80 percent of their time resting. They devoted another 17 percent to low-activity pursuits such as grooming and only 3 percent to high-activity pursuits such as hunting. Unowned cats rested just 62 percent of the time and spent 14 percent, mostly at night, being highly active. Feral cats roamed far more widely than researchers had expected: up to 1,351 acres. In contrast, pet cats stayed within an average of about five acres of home.
