A recent statistical analysis has revealed that a well-known indentation in a Chicago sidewalk, often attributed to a rat, is likely the result of another rodent. This finding comes from a team of scientists who conducted measurements on mammal specimens housed in museum collections. Understanding the true origin of this impression is important as it sheds light on urban wildlife interactions and helps clarify misconceptions about the city's rodent population.

Scientists have investigated the viral 'Chicago Rat Hole' and concluded that it was likely made by a squirrel, not a rat, as many believed. This finding is significant as it highlights the importance of accurate animal behavior studies and challenges common misconceptions about urban wildlife. Understanding the true origins of such phenomena can help in better managing city ecosystems.
