The complicated human relationship with rats is well-documented on social media marketing where wild, urban rats in cities like NY occasionally go viral for his or her consumption habits, audacity, or predilection for consuming human food.
First, there is Pizza Rat so-named as the wild rat was filmed in a now-viral video carrying a whole slice of pizza down the subway steps, while an onlooker says “live your very best life.” (Pizza Rat was later revealed to be always a hoax perpetrated by way of a performance artist named Zardulu.) In 2016, Pita Rats two rats fighting, or simply sharing, a bit of pita bread achieved similar virality. And in 2021, a video of a solo rat dragging a (thankfully, dead) crab through the subway tracks was viewed by thousands.
But these city rats, though famous to online humans, are strangers within their own worlds, in accordance with one rat expert. Indeed, the rats that you see independently, wandering round the built human environment, are technically the “losers” of their own social hierarchy. And even though we find their food-dragging antics cool, their rodent peers certainly usually do not. Understanding why takes a little foray in to the world of rats.
What is it truly like to be always a rat?
A lot of us experienced, or at the very least used, pet rats at some time; or, perhaps, you been employed by in a scientific laboratory with lab rats. Yet lab rats and domesticated rats, the forms of rats the majority of us connect to directly, have become not the same as the forms of “wild” rats that you may see in a subway station scrounging for food.
“Once you see a person rat that’s scrounging around in public areas or in broad daylight, or walking across someone’s shoe, you’re seeing what folks might characterize as ‘more desperate, disenfranchised’ rats.”
“The wild rat is really as not the same as the lab rat because the chihuahua is from the wolf,” quipped Dr. Michael H. Parsons, a rodent behavior expert, urban field ecologist and visiting research scholar at Fordham University in NY.
“The majority of what we realize about rat behavior and their direction and navigational skill capability is from lab rats in captivity, but that information from wild rats is incredibly limited,” Parsons added.
The most typical wild urban rat may be the Norway rat (Rattus norvegicus), which are prolific reproducing machines, and rats research sexual maturity in just a matter of weeks. Normally, a rat couple can make a resident rat population of just one 1,250 rats in only 12 months. Under nurturing human care, rats can surpass four years. On the other hand, street rats may live half that timeabout 2 yrs normally. And the outcast rats, just like the crab-dragging fellow, maybe even shorter.
“Rats are intelligent, sentient animals. They’re with the capacity of complex feelings and emotions, they feel remorse,” said Parsons, a behavioral scientist who focuses on academic research associated with rat pheromones. Parsons clarified that rats, which are thought to have helped spread the Black Plague in the 14th century that killed 50 million people, certainly are a public health hazard. “You will need to take rats seriously since they can make you truly sick,” Parsons added.
Parsons said rats could be grouped right into a social structure that maps onto three main groups: the alpha rats that are responsible for a well-organized rat colony; the beta rats that are portion of the rat colony; and the omega rats that are not section of any rat colony. The latter will be the so-called ostracized or “loner” rats. And these omega rats will be the ones you’re most likely to see before you on the road or in the subway.
Meet up with the omega rats
Parsons notes that alpha wild urban rats will be the highest-ranking members of these large colony and so are often well-groomed and also have access to the very best foods. He’s got observed rare “movie-star” rats who possess “excellent symmetry and beautiful, healthy coats, plus they looked greater compared to the average rat most New Yorkers see.”
On the other hand, omega rats will be the low rung on the totem pole, Parson said. In big cities, many people are most likely to come across the omega rat in the pub or, say, in the subway.
Instagram-famous rats also fuel misconceptions about rat behavior, Parsons said. Indeed, such rats are exceptions, not typical and typically are outcast rats.
“They are the vagabonds. These rats are in need of food. They need to take risks. Things aren’t going well for these rats.”
“Once you see a person rat that’s scrounging around in public areas or in broad daylight, or walking across someone’s shoe,” Parsons said, “you’re seeing what folks might characterize as ‘more desperate, disenfranchised’ rats searching for new food sources,” he said.
“They’re the ones which have been forced to visit greater distances and discover food. When humans see these rats, some might have been shunned as well as ejected by their rat colony,” said Parsons. “They’re not well-groomed. They are the vagabonds. They’re the scraggly-looking rats you may see in public areas. These rats are in need of food. They need to take risks.”
“Things aren’t going well for these rats,” Parsons continued.
These so-called disenfranchised rats, Parsons said, will be the ones which come in your thoughts when people say “never corner a rat.” If you have ever seen a wild urban rat backed right into a corner (and hopefully you haven’t had that experience first hand) these rats will most likely discover a way out. Urban legend dictates that wild urban rats can jump at you and bite that person in case you are close enough. Although it does happen occasionally, that is only a rat’s a reaction to a fight-or-flight scenario.
However, many rats, especially the sick or diseased rats, will likely discover a way to exit stage left whenever you can. Actually, alpha rats are unlikely to be on trips in public independently on a solo trip. Rather, the “alpha” rats have a tendency to travel in groups, in the same way any popular senior high school kid would.
Whether you’re coping with an angry alpha rat and its own posse or an hungry omega individual rat in the urban wild, be careful either way. The common Norway rat could jump vertically 3 feet, and horizontally 4 feet.
Parsons adds nearly all urban wild rats usually do not cover an extremely broad area geographically speaking unless they’re forced to. The common rat only travels only 30 meters, not even half of 1 city block, from its home base, he said. If necessary, rats can travel miles to get to a fresh food source, Parsons said.
In accordance with Parsons, the rats which are traveling individually farther from their homebase will be the rats which are more prone to have already been ejected from the rat colonies.

“They need to take risks,” he says. “Through the pandemic, restaurants were closed and the rats had to take chances because their regular food source was gone.”
One potential scenario that will require further research may be the evolution of city rat colonies through the pandemic when restaurants closed. As rats ran out of food sources, they could have traveled further distances. Hypothetically, other rats, including omega rats, may have began in or close to the colony will dsicover their in the past, especially when the meals sources depleted and the rat colonies dispersed or become extinct.
“We think this is exactly what happened after and during the pandemic,” Parsons said. “In order that means it may be argued that not merely do [wild] rats understand how to find their in the past to a particular location previously, however they have a memory that that has been a food source for them during the past.”
