Ratty Age Calculator

How old is your pet in rat years?

This calculator is based on a comparative age chart compiled by Debbie Ducommun of The Rat Fan Club.

The relationship between rat years and human years does not follow a constant ratio - rats develop much more quickly than humans in their early life, so the calculator shows them ageing much faster at the beginning of their lives. The unusual age of 7 for a rat is taken as comparable to the age of 120 for humans, based on an entry in the 1995 Guiness Book of Records where a lab rat called Rodney was recorded as living for 7 years and 4 months.

Bon Apetite on the Rattie Treats!

Being the wonderful rat parent that you are, you give your rats all the BEST foods and the best balanced diet right? Just think about how much you like to have an occasional treat; now put yourself in your rats “shoes”! Here are some great treat ideas for your rats!

RAT CAKE (Humans like it TOO!)

Real fast and easy to make.....doesn't look like much but is a very good cake and not *too* fattening :))
1 1/2 cup flour
1/2 cup butter (or margarine in a pinch)
1/2 tsp baking powder
1/2 cup sugar
2 eggs
1 tsp vanilla (be generous...LOVE that vanilla)

*Mix the dry, blend the wet, and then mix together. You will have a stiff lump of batter that will be difficult to spread. Bake in 9" round pan at 350F for 25-35 minutes should be very light golden brown.

*The cake will be dry and thin, the trick is in the topping.

Juice 1 1/2 oranges, 1/2 lemon, and 1/2 cup sugar. When cake has cooled stir juice and sugar constantly as you spoon slowly over cake. (Will take a while to soak in, spread evenly) This is a fantastic coffee cake, no idea what it is called or anything, but it doesn't freeze well or keep too long because of the juice, best eaten fresh within 2 days or so.

Rats adore it! Lots of sniffing noses while it bakes!

YUMMIE RATTIE ROLLS

1 tsp. overripe banana
1/8 tsp. butterscotch flavored sundae topping
1/2 tsp. (or more) toasted wheat germ
all-purpose flour as needed

*Mash the banana, and then mix with butterscotch syrup. Sprinkle with wheat germ and mix. Keep adding wheat germ until the mixture is semi-firm. Sprinkle some flour on waxed paper and shape the dough into the shape of a Tootsie Roll. Sprinkle with more flour and cut the roll into slices, using flour to keep them from sticking together. Give a slice to your rat! You can wrap any left over "cookies" in waxed paper and refrigerate them for up to four days, or they can be frozen.

PEANUT BUTTER CRUNCH
1 cup whole wheat flour
1 T. crunchy reduced-fat peanut butter
1 T. honey
1/3 cup water

*Preheat oven to 250 degrees. Grease cookie sheet (or use a spray).
Mix all ingredients with a pastry blender. Shape into 1/2" balls and place on cookie sheet. These do not spread so can be placed close together.
Bake 45 minutes; leave in oven until oven cools to dry out and be crunchy.
Makes approximately 60 1/2" BALLS

Whats in your Rattie first aid kit?

I have learned over the years of being owned by rats that it is VERY IMPORTANT to keep a Rattie First Aid Kit stocked in your home at all times. Most of the items that should be included can be purchased at a local pharmacy, grocery store, pet store, or health food store; other items you will need to get from your vet.

"So what should be included?" you ask. (I will break the list into things you can purchase from a pharmacy,grocery store, pet store, health food store, and vet.)

Before you can begin to purchase all the items for your first aid kit, you need somewhere to store it all. I prefer to keep it all in a small cabinet in my rat room so it is easily accessible. You can also keep it in a plastic type storage container, but no matter how you choose to store it, it should ALWAYS be readily available to you in case the need to use something from it arises!

Below is a list of items you can purchase from the Grocery store and Health stores. You will also need a list of items from the Vet and Pharmacy.

GROCERY STORE
Item --- Usage
Chocolate Chips --- To help wheezing / Open up constricted airways
Pedialyte / Gatorade --- Hydration
Light Corn Syrup --- Make meds taste better
White Paper Towels --- Hospital cage bedding
Tooth Picks --- Administer paste type medications
Distilled Water --- Mix pill type medications
Ensure --- High calorie intake / Keep up rats weight
Jar Baby Food --- High calorie intake / Keep up rats weight / Masking yucky tasting medication
Yogurt --- Mask yucky tasting medication (Ask your vet to be sure which meds can not be mixed with dairy products)
Socks --- Cover up surgery / wound / bandage sites

HEALTH FOOD STORE
Item --- Usage
Carob Chips --- Constipation
Bach’s Rescue Remedy --- Anxiety / Shock / Stress / Depression
Five Flower Formula --- Same as Bach’s Rescue Remedy
Phosphorus 3X --- To help wheezing / Open up constricted airways
Echinacea --- May help build up immune systems
Goldenseal --- Build up immune system / fight bacterial / viral infections / gastric inflammation / diarrhea
Grapefruit Seed Extract --- Skin conditions
Tea Tree Oil --- Wound cleaning

Only if you have a good relationship with your vet and he/she knows what you are doing concerning prescribed meds, will you be able to have these on hand.

Not each of you will need nor want to have all of the above-mentioned items in your rattie first aid kit; it all depends on what you are comfortable or not comfortable in handling in terms of rattie first aid care. As long as you have a great vet near by and have the basics of rat first aid on hand, you are off to a great start in providing your rattie(s) with the best care possible!

Critical Care of Rats and other small animals in the Home
From a lecture by Patrick E. Currivan, MVB MRCVS
Goddard Veterinary Group, London UK

When rats and other small animals fall ill, there is often a delay before veterinary advice can be sought. Patrick E. Currivan very kindly prepared these notes and gave a lecture on the best ways to nurse and care for small animals in this circumstance.

This article is designed to give basic, first-hand emergency nursing care advice to owners, and is not intended to replace the advice or guidance of your own veterinary surgeon.

Things which you can control:

Heat
Light
Quiet
Immediate Environment
Nursing
Fluids

Specific Problems:
Bleeding
Seizures
Skeletal Injuries
Respiratory Distress
Diarrhoea
Urinary Bleeding

Other Notes:
Open Wounds/Removed Stitches
Flushing out & Cleaning Abcesses

DON’T PANIC
There are a number of factors which should be taken into consideration when one finds one’s much-loved pet in distress.

It is vitally important that your initial actions help to stabilise your ill pet during that critical period before you can visit a veterinary clinic.

Kittens go squeak...not meow

If you see a litter of rats, it's best to leave them where you've found them unless you're certain that the mother is no longer with the living. Mother rats can't be with the babies all of the time because she has to go out in search of food and because her presence alone attracts predators. Rat moms care very much about the welfare of their children and will willingly risk their own lives to save the lives of their young. Not to mention, as nice or as curious as you may be, you really don't want to maintain a mom-rat's feeding schedule...trust me :o)

So, again, if you see a litter of rats, just put everything back into place and the mom will return and gather them up and move them (if she perceives their location is no longer secure) or will simply go back to her business of feeding them and caring for them. Oh, and don't worry about it if you've touched them - just like us human types, a bad or foreign smell isn't enough to make a rat mom give up on her duties.

I repeat myself because nobody ever seems to believe me: just leave them there!! Of course as humans, once we know about something, we always have to do something about it so... check up on them in about 6 hours. If mom was back to feed them, you should see a white crest through the skin of their bellies, right below their rib cage. If you see that crest, you needn't worry any longer: Mom is somewhere and she's doing her job.

If you don't see the crest, or if you know mom is no longer one of the living, here's what you need to do if you don't know of any lactating mom-rats out there.

Rat in a cardboard box...What are you thinking?

Rats are rodents. They have powerful incisors that can shred through a lot of things quite quickly. Boxes are one of those things. If you leave a rat in a box overnight, he will be gone by morning.

If you have a cage lying around for whatever reason, that may be your simplest solution. Assuming the wire spacing is no bigger than 1" X 1" it should be more than enough to contain the rat without worries of him escaping. But most people don't have cages lying around their homes...

If you have plastic tubs and/or chicken wire you can make a quick temporary cage.

Rats in the Big City

Some creatures, such as rats, never really left the city. Today, an estimated 28 million rats—which are non-native, like much of the city's human population—inhabit New York. The greater New York area is home to eight million people, which means there are more than three rats to every person. Matthews explains how it happened.

"Rats are smart," she writes. "Although a fast-forward version of natural selection has made rats in many big cities immune to nearly all conventional poisons, they still may press one pack member into service as a taster; if the test rat dies, the others resolutely avoid the bait."

Matthews says the strong adaptive ability of non-native species has begun to change the definition of wilderness. Rats were introduced into U.S. cities in the 1700s after arriving as stowaways on merchant ships. Zebra mussels, which have caused major problems in the Great Lakes by clogging intake pipes, were imported in the ballast water of international ships.

"The most important thing is to realize that a city is wilder than we tend to imagine and the land we think of as untouched or wild really isn't," says Matthews. "There has been so much human interference and reshaping that we really don't know what a pristine planet is."

Rats return to the Big City...they never left

Rat Radar: Rodent Uses Natural "GPS"

While some birds, fish, amphibians, insects, and several other rodents can use the Earth's magnetic field to assess direction when they begin an excursion, the blind mole rat is the first animal to be shown to use it to regularly correct errors as it travels.

"The change in navigation strategy [over long distances] is very interesting indeed," agreed Roswitha Wiltschko, behavioral physiologist at the J.W. Goethe University in Frankfurt, Germany. Though she says that the idea that mole rats switch from an internal map to an external reference such as the Earth's magnetic field has been suggested before but not tested.

Another study by Kimchi and Terkel, published in the November 2003 issue of the science journal Animal Behaviour, shows that blind mole rats have additional radar-like abilities to detect obstacles before they come into contact with them. Another talent human hikers would kill for.

The pair found that when they blocked wild mole rats' tunnels, the animals carefully dug out the shortest route around the obstacles to reconnect them. Furthermore, they left a safe margin of 10 to 20 centimeters (4 to 8 inches) when the obstacle was a hollow ditch, but closely followed the shape of solid concrete obstacles by just 3 to 8 centimeters (1 to 3 inches). Ingeniously, when an obstacle was placed asymmetrically across the tunnel, the mole rats always detoured it on the shorter side.

The scientists believe that the animals could be using seismic waves generated by banging their heads against the earth, much like radar, to detect any dangers that lie ahead. "It's totally clear that mole rats drum their heads to communicate and have a good sense of hearing low frequency sounds," commented Pavel Nemec, zoologist at Charles University in Prague, the Czech Republic. "And it is quite possible that they use vibrations to test proximal surroundings."

"It is amazing that mole rats live in a permanently dark environment and are able to navigate so well," added Nemec. "Other animals use sight to correct their mistakes. Mole rats use the Earth's magnetic field."

OM! Divine Rat God

Rats Rule at Indian Temple.

The floors are a living tangle of undulating fur. Small, brown blurs scurry across marble floors. Thousands of rats dine with people and scamper over their feet.

It may sound like a nightmare from the New York City subway to some, but in India's small northwestern city of Deshnoke, this is a place of worship: Rajastan's famous Karni Mata Temple.

This ornate, isolated Hindu temple was constructed by Maharaja Ganga Singh in the early 1900s as a tribute to the rat goddess, Karni Mata. Intricate marble panels line the entrance and the floors, and silver and gold decorations are found throughout.

But by far the most intriguing aspect of the interior is the 20,000-odd rats that call this temple home. These holy animals are called kabbas, and many people travel great distances to pay their respects.

The legend goes that Karni Mata, a mystic matriarch from the 14th century, was an incarnation of Durga, the goddess of power and victory. At some point during her life, the child of one of her clansmen died. She attempted to bring the child back to life, only to be told by Yama, the god of death, that he had already been reincarnated.

Karni Mata cut a deal with Yama: From that point forward, all of her tribespeople would be reborn as rats until they could be born back into the clan.

In Hinduism, death marks the end of one chapter and the beginning of a new one on the path to a soul's eventual oneness with the universe. This cycle of transmigration is known as samsara and is precisely why Karni Mata's rats are treated like royalty.

Gautam Ghosh, professor of anthropology and Asian studies at the University of Pennsylvania in Philadelphia, noted how rare this rat-worshipping temple is. "In India, as in the West, rats aren't treated with particular veneration."

In Hinduism, many deities take animals forms. "The main theological point is that there's no dividing line between what forms gods or goddesses can use," said Rachel Fell McDermott, professor of Asian and Middle Eastern cultures at Barnard College in New York City. "There's nothing to say they can't take form as a fish, a bird, or even a rat."

Ghosh noted that this temple is linked to the royal family who ruled Bikaner, a nearby city. When a Hindu royal family is seeking greater power, they look to the local cults for a patron god—or, according to London-based art historian George Michell, usually a goddess—to help them attain that power.

The male gods are not as powerful for direct involvement in people's lives, he explained, so cults surrounding local goddesses are commonly used to help sway things in their favor. "Kings who want to be powerful in India must be protected by goddesses," Michell said. This is how the Karni Mata Temple was established.

The temple draws Hindu visitors from across the country hoping for blessings, as well as curious tourists from around the world. Inside, where shoes are not permitted, tourists and worshippers alike hope to have rats run across their feet for good luck.

Eating food or drinking water that previously has been sampled by a rat is considered to be a supreme blessing. But there is one rare blessing that draws the most attention: the sighting of a white rat.

Out of all of the thousands of rats in the temple, there are said to be four or five white rats, which are considered to be especially holy. They are believed be the manifestations of Karni Mata herself and her kin. Sighting them is a special charm, and visitors put in extensive efforts to bring them forth, offering prasad, a candylike food.

Unlike the rest of the world, where rats are commonly killed for inhabiting the same space as humans, in this temple the rat residents are treated with sincere devotion. The veneration is so complete that if someone accidentally steps on a rat and kills it, they are expected to buy a gold or silver rat and place it in the temple as atonement.

For an animal that is commonly associated with pestilence and disease, this may seem strange. But during the century of this temple's existence, there has never been an outbreak of plague or other ratborne illness among the humans who have visited—which may be a miracle in itself.

Rats rule OK...

Can your Rat do this cool trick ? - Sniff out landmines


Giant African Rats Used to Sniff Landmines
Maryann Mott

Dogs have long been used to sniff out land mines in war-torn regions. But now they may have some welcome competition: rats and bees.

A Belgian company has trained African giant pouch rats (Cricetomys gambianus) to locate buried bombs, while researchers at the University of Montana are using honeybees to screen large areas for unexploded ordinance.

The efforts highlight the quest to find low-cost alternatives to safely detect underground explosives.

An estimated 80 million mines lay buried in more than 60 countries. Each day 50 people, many of them children, are killed or injured, according to the Landmine Survivors Network in Washington, D.C., an organization that provides peer counseling and prosthetics to victims throughout the world. The cost in human life is compounded by mines' impact on regional economies, where land is put off-limits to farming and development.

In Mozambique, an African country littered with land mines from decades of civil war, 20 rats were recently used to search for explosives. So far, they've been successful. In November, the animals found nine mines in one day along the Limpopo Railway, says Bart Weetjens, director of APOPO, the Belgian research company that trains the animals.

The Mozambique National Demining Institute accredited the technology in late September, allowing for the work to take place. Weetjens notes this is the first time the African giant pouch rats have been deployed in real mine fields.

The rats combed three minefields along a rail line that connects the port city of Maputo with neighboring Zimbabwe. Despite the railway's economic importance, few trains travel this dangerous stretch. People fear vibrations caused by trains will trigger the instable explosives.

Cheaper Than Dogs

APOPO came up with the idea of using rats while searching for a cheap and efficient way to detect mines. A trained rat costs about U.S. $2,000—about $10,000 less than a mine-sniffing dog. Other advantages include the rats' relatively small size (15 inches/40 centimeters), which make them easy to maintain and transport; their resistance to most tropical diseases; and their highly developed sense of smell.

"Rats are able to detect most types of mines," said Weetjens. "In principle they could detect all mines because of the explosive content, if it weren't that some devices have been manufactured with accurate sealing, which leaves no escape for explosive trace vapors. But these can easily be found with a metal detector."

Rats conditioned to TNT odors are trained to walk on a leash, which is attached to a bar that moves forward into a suspected field. When the animals smell explosive material they scratch or bite at the location. The rat's light weight—one-and-a-half to three pounds (0.7 to 1.5 kilograms)—does not trigger the mine.

A rat and handler can search 180 square yards (150 square meters) in about half an hour.

Currently the company has more than 100 rats in different stages of training at its facility in Tanzania, north of Mozambique.

Rats begin training at the age of five weeks when juveniles are weaned from their mothers. A positive reinforcement method known as clicker training is used. When the animal does something right, the trainer clicks a small, handheld noisemaker before giving the rat a piece of banana or peanut as a reward. (The same method is often used in America to train dogs in obedience schools.)

The company says the rats learn the desired task relatively quickly—between six to ten months.

"We now have some fourth-generation domestic animals. And generation after generation, the animals learn faster," said Weetjens. "It is too early, though, to conclude if this is due to selective breeding or to a more established training method and [increased] skills of the trainers."

After an animal has been fully trained, a series of blind tests are conducted during a six-week period. If the rat passes, it is then licensed for de-mining operations.

APOPO plans to use its trained rats elsewhere, including Angola, Cambodia, and Bosnia.

Thats a neat trick...Anything you can do, I can do better...

To click or not to click that is the question...

How did clicker training get started?
Clicker training uses a method called operant conditioning, pioneered by psychologist B.F. Skinner in the 1960s. Skinner observed that an animal will tend to repeat an action that has a positive consequence and will avoid an action that has a negative consequence. If a primary reinforcer (like food) is used, the animal will become conditioned to repeat the action that produces the food. Using operant conditioning, Skinner trained rats to push a lever that released food pellets. The clicker is used as a conditioned reinforcer – a cue that something good is coming. A form of clicker training (using whistles) was originally used with great success on dolphins. In the 1990s, clicker training for other animals really took off when trainers realized how easy and effective it was.

How does clicker training work?
Clicker training works by getting your pet to expect something positive (like a treat) in return for doing something you ask him or her to do. You use the clicker so that your pet will associate the treat with the clicking noise. Eventually, you won’t even have to use treats; your pet will respond to the clicker alone.

How do I do clicker training?
To start, make sure you have your clicker and some soft treats on hand, cut or broken up into small pieces. You don’t want treats that are too crumbly, since you want your pet to focus on you, not the crumbs dropping on the floor.

oh...so thats clicker training...ok good boy, sit, roll, good boy

Fall asleep while on it's back being rubbed is a good sign

It is also possible (and I think preferable) to train animals without food as a treat. I have trained lots of types of animals to to all sorts of stuff, including rats, without treats. If you use "clicker" training, I have been told to use those baby food lids instead of the clickers made for dogs because the dog clickers are too loud for rats (those are what I use but because they are free). I do lots of my training without the clicker though.

To start, I get the animal very used to me holding the animal in all sorts of positions (while petting the animal and rubbing in small circles) If you can get the critter to fall asleep while on it's back being rubbed, your on the right track. With the animal completely trusting you, you can show it exactly what you want it to do (I use a pencil sized foam or rubber stick - like those "mechanical erasor" inserts - with rodents to move paws). While you are showing the movement, say the name of that action and also have a hand signal for that movement that you are also doing. Then with a clicker make the click. When the animal does that action again, click and say the action's name and do the hand signal. Consistancy is very important. To clicker train rodents with treats, I attach a spoon to the clicker and put the treat on the spoon. Start simple actions for each command and then make those actions a little more complex. Remember a rat will likely only remember a couple dozen commands so decide before hand what commands you are going to use and write them down so you can be consistant. The key as far as I can tell, is to really love the animal first and the tricks are just a little game you add to thier petting time.

Clicker Training Rats

Are all rats trainable? Of course. Are all rats equally trainable? Of course not. Long time ago, when we were testing rats as potential behavioral models, we procured many different kinds of rats from many sources. Rats, just like chickens, come in many flavors. The rats you by at a pet store (mostly meant as reptile food) are usually unknown flavors. Some rats are better for certain purposes than other rats. If you purchase a "high activity" rat, and expect that rat to stay in one place for long, lots of luck. If you have one of those rats bred to demonstrate the onset and course of obesity, and you expect that rat to enthusiastically operate an exercise wheel, lots of luck. Having said all of that, most run-of-the-mill rats, especially the more wild-types, such as the hooded breed, are active enough to move about and condition quickly. Yes, there WILL be some exploratory behavior, especially at first. Keep the environment as constant as possible. When the rat is faced with new surroundings there is a strong tendency to explore. My guess is that the exploration is as much looking for a "back way out" as for another food source. Remember that you are dealing with a lot of evolutionary baggage when dealing with animals, and rats are relatively new as truly domesticated animals.

How can you help yourself and speed things up. Is the rat hungry enough? Especially early in the training program, rats have lots of competing "drives" going on, including exploratory behavior (for whatever reason, as I discussed earlier); finding food should be high up on the rat's list of things to do. Is the rat calm enough? Remember that Pavlov is always looking over your shoulder - handle the rat gently, and give the rat time to adjust to new surroundings. Don't train if the rat appears nervous (body kept more or less compact, head up frequently and sniffing, moving in very fast short jerks, etc.)

Suggest you get a jar lid, cover the bottom of the lid with VERY small pieces of dog food, or small pieces of whatever the rat seems to like, and ALWAYS feed the rat from that jar lid. Forget the clicker for awhile (I know, I know, people always want to go to the clicker immediately) and let the rat get used to getting food from the jar lid. Now, you can use things other than a jar lid -- a fourth- or eighth-cup measuring cup, preferably metal, works well with rats. If the handle is big enough, you may attach the clicker right to the handle of the cup (sound familiar, those of you who have been to one of our chicken training workshops?). Get the picture. First get the rat used to the idea about where food will be coming from, and THEN, give the rat the new idea of WHEN the food is available by introducing the clicker. This whole process our students will recognize, and they will also recognize that this step-wise approach to training is called SPLITTING, as opposed to LUMPING, which would mean the rat would have to learn everything all at once (adapt to environment, learn where food is coming from, the meaning of the clicker, etc.) Not having been there, and with so little info, I can't say what your problems are, but try some of the above and see if it doesn't help. Good luck.

Rat School

I know training rats may sound a little funny but it is very helpful. You can train your rat to ride on your shoulder, to use a litter box, understand when you tell it no, and come to you when you call them by name. In order to train a rat you need to establish a trusting relationship. When your rat is comfortable with their cage and you then you're ready to begin training them.

The first thing you should start with is teaching them their name. When you see your rat say its name and then hold it. You must repeat this over and over but after a while if your rat starts to come to your hand when you call them give them a treat. Soon you will be able to replace the treat with petting or a kiss.

Once your rat has learned their name you can teach them to walk on a harness and leash. I use a ferret harness becuase it can be fitted to a rats size. Training a rat to wear a harness can be kind of tricky. Before a rat will walk on a leash they need to become comfortable with a harness. When you put the harness on your rat be prepared for them to squirm and wiggle out of it. Some may even drag their bodies on the ground to get the harness off. Don't worry, this is totally normal. Make sure the harness isn't too tight, you can check this by sticking your pinky finger under the straps. If your finger won't fit then the harness is too tight. Every time you put your rat in the harness give them a treat and let them know you're still there by petting them. Don't worry if your rat looks in pain or can't walk because they will do this to try to get you to take the harness off. Once they become comfortable with the harness they will be able to walk normally. After the harness training you can attach the leash. Let the rat wander around the house a little with you following. Every so often give a little tug on the leash and call your rats name. Over a period of time start trying to get your rat to follow you instead of you following them.

I think the hardest thing to train your rat is litter training. It is well worth the effort because in the end it will save you alot of money on bedding. I use the bottom of a kleenx box for the litter box but you can find a plastic one at pet stores. Put a little bedding in the bottom of the litter box and then place all the turds in the box. Every time you see a few terds outside of the box place them in the litter box. This may take a while but it'll work. Your rat will get used to smelling the turds in the box and will eventually relize thats were they should go to the bathroom. Good luck!
