Chicago’s ‘Rat Hole’ May Be From Squirrel, New Study Indicates

Chicago, IL – A recent study suggests that what many referred to as the “Rat Hole” in Roscoe Village may actually be the footprint of a squirrel. The imprint, which became a local sensation and even went viral in early 2024, first drew attention when a photo surfaced online.

The sidewalk imprint, resembling a rat, led to countless visitors leaving gifts and tributes at the spot. However, scientists from the Royal Society found that the resemblance might be misleading after examining it against various rodent species.

On October 15, researchers stated the imprint was likely made by a type of squirrel, with the eastern grey squirrel being the most probable culprit due to its high population in the area. This analysis challenges the long-held belief that a rat was responsible for the unique mark.

Cindy Nelson, a resident who has lived in Roscoe Village since 1997, previously speculated that the imprint came from a squirrel. “I always thought it was caused by a squirrel falling from the tree onto fresh cement,” she reported.

The Rat Hole became a hotspot for social media users and tourists, with many leaving items like coins and small bottles in homage. Citing its popularity, TikTok users even posted videos showing offerings made to the imprint.

Despite its fame, the city of Chicago removed the original imprint from the sidewalk in April 2024. Currently, it is preserved at City Hall by the Streets and Sanitation Department, safely displayed in a glass case on the 11th floor.

Commissioner Cole Stallard emphasized the care taken to preserve the imprint: “Here it is. They even put a nice case on it. The people who wonder where it’s at, it’s in good hands.”
