Raccoons might be on the verge of becoming the next popular pets in the USA. Although they are known as ‘trash pandas’ due to their love for garbage bins, these ‘masked’ mammals seem to be changing due to their constant interaction with humans. This development makes them appear even more endearing, according to a recent study.
An examination of about 20,000 photos revealed that urban raccoons show a ‘significant reduction in snout length’ compared to rural ones. This is a sign associated with early stages of domestication, similar to what has been observed in cats and dogs.
Some pet raccoons have become online stars on TikTok, while a bolder animal invaded a soccer field during a Major League Soccer game in Philadelphia last year.
Presence Across America
Raccoons are found throughout the mainland. Their adaptability to both natural and human environments has placed them in a dual position: beloved in many communities but simultaneously annoying pests in others.
The increasing familiarity with humans might mean that these animals feel less fear. This suggests a weakening of their natural flight response, according to the study published in Frontiers in Zoology and presented by the BBC.
These changes likely reflect alterations in their biological ‘fight or flight’ mechanism.
‘The interaction of raccoons with humans starts from the trash,’ emphasizes Rafaela Les, co-author of the study. ‘Where there are people, there is trash — and for animals, this is an attraction.’
However, to survive in an urban environment, raccoons must adopt balanced behavior: bold enough to seek food near human spaces and ‘polite’ enough not to pose a threat.
A Process of Natural Selection
The research findings align with the ‘domestication syndrome,’ a set of physical and behavioral traits that appear in animals adapted to human environments — such as curly tails, softer features, and smaller brains.
Researchers argue that the domestication process may not have started by humans but by natural selection. The first animals that approached settlements were those with a reduced fear response.
‘Only those with weakened fight or flight responses had better chances of thriving,’ the scientists write. ‘Thus, the initial steps of domestication are likely entirely natural.’
