Check out these videos. Researchers hung a tiny camera around the neck of a few free-roaming cats, and now you can see what your cat sees as it crawls over roofs and into sewers. When they're not napping (which is most of the time), these cats are busy!
“Kitty Cams research examined the nature of outdoor activities of owned cats by monitoring pets outfitted with “Kitty Cam” video cameras. Kitty Cams allow recording of a cat-eye view without disrupting behavior. We used Kitty Cams to investigate the activities of urban free-roaming cats in Athens, Georgia from Nov. 2010 -Oct. 2011, with goals for wildlife conservation and for improving the health and well-being of pet cats.”
