HANDLING

It is never a good idea to pick up a domestic hedgehog with gloves. Although imposing in appearance, the spines are not sharp enough to cause any real injury and, unlike porcupines, the spines do not come out and they are not barbed. It is absolutely essential for your hedgehog to recognize your scent and to recognize it as being harmless. In fact, in order to show your hedgehog at a sanctioned show, you must be able to properly handle him without gloves, since these are not allowed at the show table.Handling Hedgehogs

The correct method for picking up a hedgehog is to place your hands, palms up and his head facing away from you, on each side and gently scoop him up from underneath. If you are a bit unsure at first, scoop a little lower and take some of the shavings with him as this will help to protect your hands from his spines. After picking him up, you can drop the shavings as you move him from hand to hand. Then, carefully move him over onto one hand and hold him over the back with the other. Another way is to pick him up with a slotted spoon and place him on your hand. Once accustomed to you, he won’t bother to put his spines up and he will be very easy to pick up.

If he is rolled-up into a ball, he will, in most cases, soon unroll and put his spines down. If he is stubborn, though, getting him to unroll can can sometimes be little bit tricky. The simplest and most effective means to do this is to gently rock him back and forth in your hand. He will soon pop his little head out, but if he doesn't, hold him with his head facing away from you and a little bit higher than the rest of his body. Try to figure where his neck is and, in small circles about the size of a quarter, softly rub his neck. When he peaks out, allow him to lean forward and place his front feet on your other hand. Now, you can slowly move him from hand to hand. If, after trying these methods you are still having difficulties, ask a breeder or the store where you purchased your hedgehog if they could show you the proper technique for unrolling a stubborn pet.

Obesity in Hedgehogs

Obesity, often due to lack of exercise, use of high fat foods, and too many treats, is a common and serious problem among domesticated African Pygmy hedgehogs. A healthy hedgehog looks a little rounded and plump, but hedgehogs with fat waddles at the "arm pits" or who can not roll completely into a ball are at increased risk for health problems like fatty liver disease and heart attacks. A healthy adult can weigh as little as six ounces, or even as much as two pounds, so it is important to consider how the hedgehog looks, rather than relying on a number on the scale to determine whether a hedgehog is obese. Some hedgehogs appear more prone to obesity than others, and they need a little help to maintain a healthy weight.Obese Hedgehog

The next question, of course, is how! According to research presented by Dr. Susan Graffam of the Bronx Nature Conservatory at the Go Hog Wild Hedgehog seminar in 1998, an average hedgehog needs about 30 to 70 calories a day. That really isn't a whole lot of food (about 1 to 4 Tbsp.)! Some hedgehogs will gorge if given the opportunity to eat a lot of a food they really like. There is a published study citing a hedgehog who was free fed mealworms and nearly doubled its weight in a very short period of time. A sad but classic example of this problem is a hedgehog who was known as Big Bob. Dawn Wrobel tells the story of how she went to pick up a rescue hedgehog whose owner said she would kill the hedgehog if someone didn't come get it right away. Dawn quickly rearranged her schedule and arrived to find the most obese hedgehog she had ever seen. When leaving with Big Bob, the previous owner said, "Don't forget to give him his treats." Dawn asked, "Treats, what treats?" The lady said, "Oh, I feed him a chocolate bar every day." Bob got no more chocolate after that day, and went on to lead a much healthier life. Some hedgehogs, like this one, manage to get their svelte figures back just through cutting back on their treats or switching to a lite brand of food.

Some hedgehogs do not seem to lose weight easily, even when food is cut back and a wheel and/or large amounts of space are provided for exercise. Our Tater tends to have this problem. Tater looks healthy at about 20 ounces, but last summer when we thought she was pregnant, she ballooned to 27 ounces. And she was not pregnant, just eating for a whole zoo, it turned out. I cut her food back to 1 Tbsp. Per day, but she still did not lose weight. I cut her back to 1 Tbsp. of lite food per day, and she lost just a mere half ounce. I finally began to count out the number of pieces of food she was getting each day, and scattered them around the cage to force her to move.

She finally started to lose weight! Once the weight started to come off, she began to move more, getting back to running on the wheel and exploring around her cage at night. After three months, she was down to a lovely 19 ounces and we were able to begin to up her food intake. We have heard of other hedgehog owners who encouraged obese hedgehogs to exercise by providing supervised swim sessions, though out of shape hedgehogs can tire easily to caution should be exercised with this approach. When in doubt, consult your veterinarian, and keep in mind that a healthy hedgie is a happy hedgie.

Giving Oral Medications

This document was originally written after I had to give one of my hedgehogs oral antibiotics for a bacterial infection of the skin for an extended period of time.

I have since used many of these methods depending on the hedgehog I am dealing with. When some hedgehogs don't feel well they will willingly allow you to medicate them, others become very defensive and stay curled up in a ball, making medicine time quite an event.

Depending on your hedgehogs attitude and how comfortable you are handling a sick hedgehog, you may find some of these methods easier than others. I highly recommend trying methods 1, 4 & 5 first. If those fail then you will need to move on to a more forceful approach.

Method #1
First offer the medication to the hedgehog from the syringe. Many oral medications are flavored, thus your hedgehog may readily lap the medication from the syringe.

Method #2
Wrap the hedgehog in a towel (not balled up) with its head sticking out of the towel. Then place the syringe in the corner of its mouth. Normally the hedgehog will open up to bite the syringe. You can then squirt the medication into the back part of its mouth and the hedgehog should swallow the medicine.

Method #3
Allow the hedgehog to curl up in a ball by rolling it on its back. Then when the hedgehog starts to uncurl place your thumb under its chin so that they can't ball back up. This may take a little pressure to prevent. Then place the syringe in the corner of the hedgehogs mouth . Once again the hedgehog will probably open its mouth to bite the syringe. You can then give the hedgehog its medication.

Method #4
Mix the medication with a treat. Find a food that the hedgehog really likes. Mix 1 part medication to about 2 or 3 parts of the treat. Don't mix the medication in normal food due to the fact the hedgehog may decide it doesn't want to eat its normal food anymore because of a bad tasting medication.

Method #5
Inject the medication into food items (mealworms, corn, etc). I have found injecting oral antibiotics with a small needle into a mealworm then feeding the hedgehog the mealworm to be really effective. Make sure to offer another un-medicated treat to get rid of the "nasty" taste.

Am I Allergic to Hedgehogs?










While most people do not suffer an allergic reaction to hedgehogs, some still do and in almost all cases, it appears to be an allergy to the saliva.

There are, however, other things to watch for. If you have an allergy to a hedgehog's bedding material or to other animals, this can also cause problems since a hedgehog's quills will push the offending substances just below the surface skin on your hands and create a reaction that wouldn't otherwise occur.

As an example, if I pet a cat I have to be sure not to touch my nose or eyes, but otherwise I suffer no serious symptoms unless the room is full of cat dander. However, if I first touch a cat and THEN pick up a hedgehog, the hedgehog quills push the cat dander into my hand and my hands swell up, covered with ugly red welts.

To find out if you are allergic to hedgehogs, it is best to take a look at some hedgehogs, pick up a few nice and friendly ones and see if you have a reaction. A slight itchy feeling on your hands afterwards is ok and (dare I say it) almost normal. Just watch out for signs of swelling or red welts.

Hedgehog Skeleton

Hedgehogs have a fairly typical mammalian skeletal structure, but with much longer hind and fore-legs than most people imagine. The skull is broad and blunt with well-developed cheek bones. The jaw can exert a surprising amount of force do to the musculature attachment being located well-forward of the cheek bones.  The cranial cavity is small, but contains a brain that, while primitive in many aspects, is surprisingly more complex than first observations suggest.  Dentition consists of  36 teeth which are highly suited to both an insectivorous and omnivorous diet.

COMMON AILMENTS
Wobbly Hedgehog Syndrome (WHS) A genetic disorder that causes progressive paralysis similar to the human form of MS. There is no cure and the afflicted hedgehogs slowly and eventually become totally paralyzed. The disease appears to be carried by a recessive gene making detection and eradication difficult. Breeders should avoid using hedgehogs with any WHS in their family lines.
Cancer Hedgehogs can suffer from cancerous growths and lesions to the same extent as other comparable species. Common to female hedgehogs are ovarian, uterine and mammary tumors; and to males, jaw and testicular tumors.
Eyes Eyes can be lost to quill pokes, most commonly when multiple hedgehogs are housed together. Infection is common if not treated immediately.
Teeth Tooth loss and wear can occur in older hedgehogs. Weight loss can occur in extreme cases. There is some speculation that an all-hard food diet can cause premature tooth wear. Hedgehogs with poor dentition should be fed a soft food diet to compensate and prevent weight loss.
TERMINOLOGY
Males Males
Females Females
Young Hoglets or pups

Quills Quills or Spines
Anointing or Self-Anointing The act of frothing at the mouth, arching the head back over the shoulders and depositing the frothy saliva onto the quills. Triggered by pungent smells and new tastes. The exact purpose of anointing is unknown.

KNOWN YOUR HEDGEHOG

It has been said that no other exotic animal has caught the attention of the public quite like the pet hedgehog has. Their spines, friendly and curious nature, as well as that ever-smiling expression have endeared them to millions of confessed hedgehog lovers around the globe.

Those in Britain, Europe and parts of Africa have long known about the hedgehogs’ charm. British author and illustrator, Beatrix Potter, although most famous for her story of Peter Rabbit, also wrote the wonderful tale of a hedgehog named "Mrs. Tiggy-winkle", a matronly washerwoman. A British wildlife hospital dedicated to rescuing sick and injured hedgehogs is even named after this delightful character.An introduction to hedgehogs

The interest in hedgehogs doesn't end there, though. Until recently, these remarkable little animals were virtually unknown in North America. But now, thanks to the pioneering efforts of breeders, the African Pygmy Hedgehog is now readily available and can be found in the homes of thousands of happy pet owners. "But why," you may ask, "is there such an interest in hedgehogs as pets?"

Besides having a peaceful and humorous nature, hedgehogs readily lend themselves to just about anyone's lifestyle and schedule. Being diurnal (awake parts of both day and night) just like house cats, nearly everyone can find a time of day in which to enjoy them. They do not require a great deal of room in which to live and their dietary requirements are very easy to meet and, since they are solitary animals by nature they neither require nor want the companionship of another animal.

Unlike hamsters, Guinea Pigs and other small rodents, pet hedgehogs do not give off any appreciable odor and they are easily litter trained. They live much longer than rodents, too. With the proper care and diet, your pet can live to be 4 - 7 years old. Add to all of this the fact that they require no immunization shots and are very disease resistant and you can see why so many people consider hedgehogs to be the perfect pet.

They have adorable little raccoon-like faces, set with beady little black eyes and small pointy noses that seem to twitch constantly, checking out the different odors of the room. Depending on the color variation that you choose, their little white faces may or may not have a mask. Although not related to the porcupine, they are sometimes mistaken for them because of the quills that cover their backs. The similarity ends there, however, since these quills are not barbed or nearly as sharp and remain attached to their bodies. Their little white tummies, on the other hand, are extremely soft and are covered with short, white hair. When frightened, they can roll up into a tight ball and look very much like a sea urchin. They have a short, stubby tail, but this is rarely seen since they keep it tucked up close their bodies. With their tiny little legs and round bodies, it is a real sight to see them scurry across the floor

African Pygmy  HedgehogUnlike their much larger English cousins, the African Pygmy Hedgehog (or pet hedgehog) is rather small in size, with the average adult weighing between ½ and 1 ¼ pounds and are 5 to 8 inches long - about the size of a Guinea Pig. There are a few rare adults that will grow to as much as 1 ¾ to 2 pounds (without being fat) while others are as little as 6 or 7 ounces. Breeders are now concentrating on these differences so that someday, we will have a choice between two different sizes of hedgehogs.

They have a quiet, gentle, disposition that makes them a true delight to own and hold. Each has a distinct personality and will bond to its owner for life. (We are assuming you purchased a socialized pet). They are surprisingly intelligent, fun to play with and are easily entertained. They love to play with tunnels, mazes and specially designed hedgehog wheels. Even something as simple as a toilet paper tube will make a good toy, as they love to stick their heads in them and run about the floor. Despite their solitary nature, they can become very affectionate with their owners and will even enjoying watching TV with you or just snuggling in your lap.

Because they are quiet, they are very easy to travel with. Most people aren’t even aware that a pet hedgehog is nearby. Many hotels that restrict other animals such as cats and dogs will allow hedgehogs. Once trained to a litter box, an adult can pretty well have the run of the house. With its excellent sense of smell, keen eyesight and good memory, it will know where the litter box is and will use it on a regular basis. Because they are not a rodent, they have no body odor, but it is still important to clean the litter box daily to eliminate all smells. Some people are not comfortable with a loose pet, so a cage with a minimum floor area of 16 x 24” will keep it happy and secure.

Hedgehogs truly are a low maintenance pet. Your pet hedgehog should be kept indoors at normal room temperature (65 to 80oF); it can be fed a good quality dry cat food or a specially formulated hedgehog food; they don't bark, although when happy, some will emit a quiet purr; they do not climb curtains or chew on furniture; and, they do not ask to be taken out for a walk. All that your pet asks for is to be fed and watered, loved and appreciated. Besides simply being enjoyed as pets, there is also an active hobby.

Thanks to the efforts of the hard-working folks at the International Hedgehog Association, (IHA) there is now a working show system and standard of perfection for the pet Hedgehog. Breeders and pet owners alike can now show their pets in friendly competition. As well, many breeders are involved in the fascinating and challenging world of color breeding. Many beautiful new colors have already been produced and many breeders are hard at work to produce even more. This adds a whole new dimension to owning hedgehogs and even those with only one or two animals are becoming actively involved.

ABOUT HEDGEHOG

About  HedgehogsHedgehogs are a lot more than just another pretty face. Their contribution to history, folklore and even medical knowledge is extensive. Despite all of this, the lowly hedgehog has remained surrounded by an aura of mystery and superstition. Oftentimes misunderstood and maligned, it is only in this past century that hedgehogs have come into their own, becoming popular in literature, and now, since the early 1990's, being kept and even revered as domestic pets.
