A strange image of a little entrance inside a house went viral on Reddit earlier this year, igniting curiosity and rumors. Some individuals made amusing guesses about it being for mice or fairies, while others offered more sensible justifications.
Denver’s Tiny Door

According to Colonel424, their mother-in-law lived in Denver, Colorado, and had multiple little doors that were each roughly the size of a soda can. Many people were curious about the function of these little doors because of the old house’s distinct appeal. Some users claim that these doors were intended to be pet doors, especially for cats. “If it’s actually the height of a soda can, then it’s a cat door,” a commentator said.
Verifying the Goal
According to an additional explanation, tiny entrances known as “cat flaps” were carved into doors in the early 1900s to let cats go from room to room. This was carried out to aid in mouse population management. “My grandmother grew up in one of these homes and told me stories of this,” a user commented from their own experience.


Although the explanation about the cat door makes logic, numerous Reddit users offered further applications. Some believed they would serve as children’s fairy doors, encouraging imaginative play. Others hypothesized that they might be utilized for heating and cooling or as a component of a drainage system. Even without a dustpan, one user proposed that they were for sweeping debris outside.It’s interesting to note that these little doors appear to be exclusive to America. Such doors are uncommon in Australian dwellings, according to Australian history specialist Scott Lucas. He clarified that whereas Australian homes usually had cellars, older American homes frequently had entire basements.
Mysterious elements typical of the age in which they were developed can be found in old dwellings. Although many of these characteristics are antiquated now, they provide dwellings a distinct charm and historical significance. The little door is the ideal illustration of how even something small can provide a window into the past and pique interest in its intended use.
