Researchers strapped cameras on 16 cats and let them do their thing

In a study published this month in , the behavioral ecologist at the University of Derby in the United Kingdom placed small cameras on 16 cats and followed them for up to 4 years as they prowled their neighborhoods. A: A couple of other studies had put cameras on cats, but they tended to only look at one thing: how often cats cross roads, for example, or how many animals they kill. If we find that cats seem more bored or stressed out when kept indoors—for example, by pacing, like some animals do at the zoo—that means we need to think more about enriching their indoor lives, or giving them some outside time.
