It's a common belief that the Black Death spread through parts of the world partly thanks to rats (and their fleas) climbing aboard ships and infecting people in distant lands. The plague is caused by Yersinia pestis, a bacterium with a 30 to 100 per cent mortality rate, if left untreated. Now, scientists believe it was more likely body lice and hu...
If you're bitten by a bat, fox, raccoon or even a cat or dog, you're usually treated for rabies after as a precaution. Not so in the case of a rat bite, said Corrigan. The brown rat is unlikely to transmit the rabies virus in North America. Rats are more likely to transmit other pathogens like salmonella, E. coli and the potentially deadly disease ...
Wrong! Rats live everywhere. We tend to associate rats with the lower-income areas of cities. Deteriorating and poorly maintained buildings are often filled with cracks and crevices that allow rats to move in and out, and they may have more access to our garbage due to illegal dumping or improper disposal. But rats are opportunistic creatures. If t...
In 2015, a photo supposedly of a 19-kilogram super rat caught in New York City made the rounds. It's not the first time "rodents of unusual size" (for those familiar with The Princess Bride) have been rumoured to scurry among us, but the truth is that monstrous city rats are fiction. It's possible the image was of a large pet rat photographed with ...
Rats' sharp incisors never stop growing. As rodents, their teeth are key to their success, allowing them to gnaw through all manner of materials — just not stainless steel. Their chompers are attached to strong jaw muscles and their chisel-like teeth can gnaw away at many materials, like wood, vinyl, plastic, drywall and even brick and aluminum if ...
Some fear the milder winters resulting from climate change could cause rat populations to explode, making it impossible to keep them in check. Given that a single female brown rat has the capacity to produce 15,000 descendents in a single year, it's a scary thought! But before you scream in anguish, be reassured: it's unlikely we'll be overrun. Whi...
- Rats can squeeze through extremely small holes. A rat can squeeze through a hole the size of a quarter, thanks to its collapsible skeleton. Its ribs are hinged at the spine.
- Rats can chew their way through almost anything. Rats can chomp through thick wood, metal pipes, brick walls, and cement. Their front teeth are long—they grow about 5 inches every year—and also very sharp, with a nifty self-sharpening feature: The edges of the upper and lower teeth rub against each other, having the effect of a knife on a whetstone.
- When rats bite, they mean business. Rats will usually only bite when cornered. But then they bite hard—very hard. Their jaws are built like an alligator’s and can exert as much as 7000 pounds of force per square inch—which means their teeth can easily slice down to human bone, as one state biologist in New York discovered when he picked up an errant lab rat with his hand.
- Rats are superb athletes. The long claws on a rat’s feet allow it to scale brick or cement walls with Spider-man-like ease. Getting down isn't a problem, either: A rat can fall 50 feet and land on its feet without injuries.
Rats are often used to study behaviour in psychology experiments. Their brains are larger than mice, and the animals are less timid and more intelligent. Although rats do not ‘think’ like humans, some of their brain structure resembles the more primitive elements of human brains, and hence they can be used to model some human behaviours.
Jul 1, 2012 · Do animals other than humans have a sense of humor? Perhaps in some ways, yes. But in other ways there are likely uniquely human properties to such emotions.

Rats are notorious stowaways that migrated around the world along with humans; today they live wherever Homo sapiens are found, on every continent except Antarctica.
Feb 2, 2020 · Rats cut deals and trade favors, dream of a better future, read others' pain, laugh, and like to be tickled, yet aren't considered animals by the Federal Animal Welfare Act.
