Interesting Facts About Rats

When most people think of rats they think of sewer rats or the plague but, actually, these ingenious little creatures have been marching at our side since the beginning of civilization and not everyone detests them so much. In fact, there's lots of reasons to love them including their colorful history of living with us.

  • Our current domestic strain of rats likely began in England in the seventeenth century. Jack Black, the royal rat catcher to Queen Victoria was rumored to have bred the first albino rats in captivity. Before this rats were killed as vermin, used as food in times of plague, and captured live or bred to use in a sport called rat baiting where one dog was challenged to kill as many rats as it could in a certain time period. Albinos may have been encouraged in captive specimens because they show blood better but it wasn't long before they started becoming pets for ladies of high learning.
  • Sprague Dewley are a well known laboratory strain that was developed to produce very large litters, sometimes containing more than twenty pups!

Rat Performing Tricks

  • Most rats in captive populations are a domesticated strain of Rattus norvigicus. These animals probably originated in Asia but they were so good at jumping on our ships and travelling with us to new lands that we may never be able to trace back their original country of origin.
  • Sometimes also found in the pet population Gambian Pouch Rats are an African species that can weigh more than 8 pounds in adulthood. These rats are so intelligent that they have been trained to sniff out mines in war torn countries.
  • Fancy rats usually live anywhere between 1-3 years of age with 2 probably being average. However one remarkable rat who died in 1995 made it into the Guinness Book of World Records by living for seven whole years and four months!
  • Rat math: Female rats can sometimes breed as early as six weeks of age and can have back to back litters every month until she's between one and a half and two years of age. That means one female having litters of eight pups each could have more than 180 babies in her life!
  • The Black Death, or Bubonic Plague, has long been blamed on rats but it really wasn't the rats who caused it. Instead it was an organism living in the fleas that the rats carried. When an infected flea bit a human it was usually curtains for them. The Bubonic Plague still exists and there are an average two cases per year in the US, although the advent of antibiotics has made it much less deadly.
  • There is a temple in India called the Karni Devi that has housed thousands of rats for hundreds of years. Far from being pests the temple was built for them and the people who visit worship them as their reincarnated ancestors. Albino rats seen in this population are believed to be the Goddess Karni Matta or her sons. People share food with these rats, walk barefoot through their temple, and if they kill a rat, even by accidnet, they must replace it with a life sized gold rat statue. Curiously while the black death swept through the area people in the temple never fell ill - this is likely because the local healthy population of rats kept out infected intruders.
  • Rats were one of the first animals sent into outer space. In 1961 the first rat to see outer space was launched from France.
  • The yellow teeth of a rat show their maturity, as babies initially have white teeth. These tough teeth continue to grow for as long as the rat lives because if they didn't the rat would file them down to nothing which would eventually ause starvation when it could no longer chew its food.
  • Conrad Gesner was the first to record the appearance of wild albino rats in the Western wold when he spotted two in a cemetery in 1553.
  • Rats entered the laboratory for the first time in 1828. Albino, black, and piebald (those displaying white) were favored over their brown wild type counterparts.
  • The Wistar Institute in Pennsylvania started the first inbred laboratory strain which remains today one of the most popular strains to inhabit laboratory settings.
  • Cloning in its most rudimentary form was first practiced with these inbred strains. Rats were mated brother to sister until all resulting offspring were 99% genetically identical. In case you're wondering, that's at least 300 generations of rats. Even real clones aren't that identical to each other.

Gambian Rats Finding Land Mines and Detecting Tuberculosis

  • Early sleep studies involved tireless researchers poking rats awake to see the effects. At the time people did not know what the role was sleep was but they didn't think a lack of it could kill you. During the experiment the rats that they kept awake steadily declined in health as well as emotional attitude. They became aggressive, disoriented, lost chunks of hair, formed lesions on their feet and tails, ate more but lost weight, and eventually their internal organs went completely haywire and after 17-20 days they'd finally find the sweet mercy of death.
  • A more humane study has found that rats laugh, or at least they make a noise that resembles laughter in its meaning. The rats studied made these noises (undetectable by the human ear alone) when tickled.
  • Mice and rats weren't always considered two different creatures. Surely the Romans didn't feel they were, instead calling them Rattus Major (big rat) and Rattus Minor (little rat.)
  • There are at least 4 genetically unique strains of furless rats within the laboratory setting as well as in the pet trade. In thepet trade they're often call Sphynx.
  • Rats use their whiskers to feel where they are going because their eyesight is too poor to be of much help. This is why you'll rarely see one out in the open where its whiskers aren't touching a border of some sort. This would leave them vulnerable to hawks and other predators.
  • Humans have employed rats as laboratory assistants, as companions, as religious icons, as characters in popular fables, and they have even taken on the jobs of feeding the desperately poor with their meat, finding potentially live mines, and some have even been trained by electricians to drag wire through walls.
  • Legend dictates that rats are to be the first animal on the Chnese Zodiac.
  • Rats cannot vomit or sweat. Most rats use their tail to get rid of excess heat. Tailless rats don't ave this luxury so if you have on of those keep them cool!
  • The royal rat catcher of Queen Victoria, gave an albino rat to Beatrix Potter, the author of the much loved Peter Rabbit series. She was one of the very first pet owners of such animals and she even put this beloved pet into at least one of her stories.

If you have an interesting or unusual rat fact, let me know and I'll add it! All photos were taken by me of rats I've bred over the years at the Oh Rats Rattery.

      No problem. I know it's difficult sometimes. I had rats for many years- had to give them up because I developed a fierce and worsening allergy to them. I still miss them and although I've gone onto other things they'll always reside in a special place in my heart. Personally I found them to be more personable then a lot of dogs I've met. It's a bleeding shame they don't live very long. Right before I developed my allergies I was waiting for the Monkey Pox Ban to break so I could get a breeding pair of Gambians legally. They live up to 7 years.. but alas, that took too long to happen. Not even sure if anyone has them in the US any more, besides of course the feral colonies in the Everglades, dumped at the onset of the Monkey Pox Ban by pet shops who knew they could no longer sell them. DUH! People sometimes....

      I am not sure what you mean by that question. The first generation of lab rats were born to captured wild albino and a wild agouti-colored rat. The first generation would have been albinos and solid agouti in color. If this isn't the question you asked just rephrase and I will give it another go. :)

      My pet rat, Applelonia, would come out at night and search my face for any abnormality. She would remove scabs without damageing the underlying tissue - a practice which my doctor, unaware, later instructed me to do in order to prevent bacterial infections. Luckily, she didn't catch any deseases from me (smile).

      I have never heard of that behavior parveen. Perhaps you just have a quirky rat or maybe she's just grooming as rats often do. I had a rat that would get his paws wet and then lick up the water off them, maybe this is the same behavior?

      Hi, I would live to have a rat :) I've researched them now for over 2 months and I've never neglected my pet that I have now which is a bird that I bought out of my own money. They sound like amazingly fun lol critters.

      I've talked to my mother and she just says "no they are disgusting dirty creatures!" I've tried sharing some interesting facts about them like intelligence and cleanliness and traits, but she still hates them.

      I have saved up more than enough money to buy a cage 2 female rats, toys, food etc but I haven't come straight out an told her I want a rat yet, because too soon could ruin my chances altogether. Please if ANYONE has any tip on how to make her at least not mind rats I would be extremely grateful!!!

      Rats really are amazing creatures! I have two. One I got about 6 months ago now and the newest one about a week ago. and when I got her I had a feeling something was up because the size of her belly but i wasn't to sure if she was pregnant or if she was just fat. And today I walk into my room to find little pinkies all over the cage! It's very cool to watch her nurse her babies and i'm definetley adding one to the family! for the rest, (6 others) I have already found wonderful homes for. THE ONLY thing I have against rats is them tearing up my furniture! I cant let my eyes of them without them getting themselves into trouble. perhaps a male rat is more for me!

      Rats also excreate a blood like supstance from pores around their eyes when stressed. This happened with my PEW named Blood(coincidently), about a year after I've had him, and this was shocking. So I looked to see why that happened and it turns out its nothing to worry about.

      Rats are really good pets. All people, who hate rats just have no experience of close interaction with them and also just afraid of it. I may agree that wild rats may be unpleasant, but pet rats are the different. I guess, that any mammal animal have it's own charm, and pet rats not the the worst of them.

      A rat, similar to a cat, has the ability to fit its body through any opening its head will fit through.

      A rat can tread water for two days before drowning.

      A rate can swim for several miles before tiring and drowning.

      A rat can chew through materials such as copper and concrete. While it takes a considerable amount of time, and puts an enormous amount of wear on their teeth, the rat will usually accomplish their goal, as their teeth continually grow.

      A rat has the ability to "shed" the skin from its tail in times of duress, such as when the tail gets caught in an opening, under a fallen or heavy object, or when in the jaws of a predator. The skin will grow back, but the rat is particularly prone to infection during this time.

      When facing an opponent, a rat will stay very close to the target. Due to their poor eyesight, they will fan their whiskers forward and attempt to keep in contact with their foe.

      Nicole, You can buy a bottle of scent remover from your local pet store that will get rid of the smell. Just add three drop[s to your rat's water bottle. you should notice a difference in a few days. You can also mix baking soda in with their litter. two or three table spoons should help.

      2 nights ago i witnessed a rat glide or fly from a tree to a light pole, climb to the top of the light pole and then glide to another tree. My question is there such a thing as a flying rat? or is there another type of rodent that flies but looks like a rat. Unfortunately i don't remember much about the tail, but it definitely looked like a rat. If you don't know or haven't heard of such a thing could you tell me where i might find out? I live in central Florida.

      i might be getting a rat soon and i know a bit about them one fact i know is that a boy and a girl ratcan make babies in two seconds! another one is that a female rat goes into heat every four to five days! rats reach pubity at six to eight months. rats can eat chocolate but they try to avoid it so dont force them to eat chocolate.

      hi i have a rat fact for you. Rats tails are sensitive. rubbing a rats tail is like some one rubbing the bottom of your foot.

      Hello. I have heard this before and wanted to know if you could confirm it. I have heard that if you have a rat in your home, as pet or otherwise, a mouse will not enter. Is that true?

      I have been watching a family (1 female and 5 juveniles) of wild rats every day where I work. I saw the mother nip the backside of a pheasant and chase a rabbit! This family is so cute, all this goes on 2 mtr from a window. Awesome. x
