Rats!


Once upon a time there was a kingdom filled with rats.  Luckily the villagers were able to hire a pied piper to lead the rats away from the kingdom, and all was saved.

Of course they could have saved themselves money and having their children kidnapped if they had encouraged birds of prey to live there instead.  Rats and raptors go hand in hand like cats and cream.  Most birds of prey eat rodents like rats or mice.  
Rat meat is one of the most nutritious of all the foods that we feed our birds and it is definitely their favorite.
Rats are very important at World Bird Sanctuary, but not all rats are food.  We have five rats at World Bird Sanctuary that help to educate the public about their species and the importance of raptors in the food chain.

Nimh, Templeton, Triscuit, Skittles and Jellybean all reside at World Bird Sanctuary.  Triscuit can be found in the Nature Center and in various educational programs, like Creatures of Myth and Legend.

Nimh, Templeton, Skittles and Jellybean live in our behind the scenes area and travel with us for the educational programs we present at zoos, theme parks and aquariums.  There they run on grape vines before each show as a kind of comic relief.  Training them to run on these grape vines only takes a few weeks.  Most people do not realize that rats are fairly intelligent and can be trained easily to follow a target, run a maze, and in some cases to use a litter box.
Rats are a very important part of our Education Programs
All of our rats are very sweet and love being handled, especially Nimh and Templeton who love to climb up onto our shoulders and sometimes hide in our hair.  Rats make excellent pets, though they usually only live about 3-5 years.  They are easy to care for, needing only a cage, water bowl, a place to hide and a few toys to play with, and of course an exercise wheel.  Nobody wants a fat rat! Most importantly though, they need things to chew; all rodents, from the South American Capybara, the world’s largest rodent, to mice, need to chew because their incisors (front four teeth) are constantly growing.  Chewing hard objects, like the shells of almonds, helps to keep the incisors at a healthy length.  Their incisors are also used to shred up objects for nesting material.
All of our rats enjoy being handled
Rats are amazing!  Those tiny teeth of theirs are not only constantly growing, but they can also cause quite a nasty nip.  Rats have 24,000 pounds per square inch of biting power and they can even chew through a solid steel drainpipe…with their teeth!  Rats are excellent swimmers and can tread water for up to three days.
 
Have you ever wondered how mice get into your house?  They have collapsible skeletons and rats can fit through a hole the size of a quarter—mice can squeeze through a miniscule hole! 

Rodents are unable to throw up (the body’s way of purging toxins), so rats must take tiny bites of all of their food to make sure it is safe to eat.  They are one of the only other animals besides humans that are able to digest chocolate.
 
Rats are prolific breeders!  A pair of rats, their offspring, and so on, and so on, without any controls on their population, is capable of producing over 1,500 more rats in only one year if they all survived.  Imagine 1500 rats running around in your home or yard; sounds kind of scary doesn’t it?  This is why birds of prey are so important; many different species of birds of prey eat a steady diet of rats and mice, which helps to keep these populations in check.

As Nimh, Templeton, Skittles and Jellybean run across the grapevine, they not only make people giggle (or scream), but they teach them important lessons about how we need birds of prey around, not only for ourselves, but also for the good of the environment.

The Rat

Most people react with a shiver of fear when a rat is mentioned; but there are some people who love rats.
Rats are cute, intelligent and can make great pets
I am part of the second group.  I have had rats as pets for years and love to spoil the rats we have here at the World Bird Sanctuary.  And why would we have rats at a bird sanctuary you ask?  Well, one of the things we do here is education, and since rats have some of the worst reputations around we try to separate fact from fiction about these much maligned animals.  Some of the bad reputation is deserved, but some is not.  Rats are really fascinating animals.  Here are some of the facts:

* There are 51 different species in the genus Rattus
* Rats did not cause the Black Plague--they did, however, carry the fleas that carried the disease--when the fleas jumped from rats to people and then bit them, the disease was passed on.
* Rats are originally from Central and Southeast Asia--but they are so adaptable that they are now found everywhere in the world.
* A group of rats is called a mischief (how appropriate!)
* Rats cannot vomit--once they eat a poison, they can't get rid of it.
* Most pet rats are domesticated descendants of the Norway, or Brown, Rat.  These rats were originally from China, spread throughout Europe and finally came to the US around 1755 aboard ships from Europe.
* Rats are excellent jumpers--they can jump 3 feet vertically and 4 feet horizontally!
* Rats are tough--they can take a 50 foot fall without being killed or even seriously injured!
* Norway rats can swin 1/2 mile and dive down through sewer pipes and water plumbing traps--even swimming against a strong current!
* It is estimated that there is approximately one rat for every person in the U.S.
* Rats do not like cheese--in fact, they are lactose intolerant!
* The hairless tail of a rat (which creeps out so many people) is important to the rat for temperature control, because they cannot sweat.
* A rat's teeth will grow continuously throughout its life, as with all rodents.  They must always chew on things to keep them ground down.  In fact, a rat can chew through a lead pipe!
* Beatrix Potter, the author of Peter Rabbit, was one of the first owners of a pet rat--an albino bred by none other than Queen Victoria's royal rat catcher, Jack Black.
* In northwestern India, the rats at the Karni Mata Temple are highly revered.  The priests feed milk and grain to the rats, and pilgrims that visit the temple also eat this food.  In fact, in India, eating food that has been touched by rats is considered a blessing from God.
* The ancient Romans did not generally differentiate between rats and mice, instead they called rats Mus Maximus (big mouse) and mice Mus Minimus (little mouse).
Saltine & Triscuit, our two resident education rats
All in all, rats are fun, intelligent, clean and clever animals.  If raised correctly, they make great pets and are a blast to work with.  If you visit us at the World Bird Sanctuary, please ask to visit with our resident rats, Saltine and Triscuit.  They live in our Nature Center animal food preparation area (the only reason they aren't out in the main room is that we ran out of room)!  They are really sweet animals.
