Summarize the following:
Don't house the hedgehog under your stereo player or television. As a prey animal in the wild that depends largely on its sense of hearing, your hedgehog will find too much noise and activity very distressing. Ensure that noise, lighting and activity levels are low in its vicinity and move the cage if the noise levels increase for any reason. Hedgehogs can get used to noise if introduced gradually. Hedgehogs are prone to putting on weight, so exercise is a must for them. This means plenty of toys, along with its hedgehog wheel. Toys should be something they can chew, push, nuzzle and even tip over, as long as they cannot chew pieces off or swallow. Be sure their nails or feet can't get caught in any loose strings or small holes.  Possible toys include: rubber balls, old kids' toys, rubber figures, baby teething rings, empty toilet paper tubes cut in half lengthwise, cat balls or bird toys with bells inside, etc.  Let your hedgehog play in a larger playpen occasionally. You can purchase a large plastic tub or let it explore your bath (without water, of course). Hedgehogs are notoriously good at hiding ailments, so it is extremely necessary to be aware of your hedgehog. Keep track of any changes and call your vet to see if there's something that needs to be checked out.  If your hedgehog doesn't eat for one or two days, something is wrong and it needs veterinary attention. Hedgehogs that go for a few days without food are at risk of developing fatty liver disease, a life-threatening condition.  Watch out for scaly, dry skin around the quills: this could be a sign of mites, which can be debilitating if left unchecked. Wheezing or crackly respiration as well as discharge on the face or wrists are signs of respiratory infection, a common and serious condition in hedgehogs. Soft stools for more than a day, or diarrhea combined with listlessness or lack of appetite can be signs of a parasite infection or other illness. Hibernation, though occurring in the wild, is not safe for hedgehogs living in captivity. As mentioned above, if your hedgie feels cool on the belly, try to warm him by putting him under your shirt next to your skin. If he does not warm within an hour, bring him immediately to the veterinarian's. A hedgehog's familiarity with being held comes with being handled frequently.  Always be confident when handling a hedgehog: they are not as fragile as they seem. The general rule is at least 30 minutes a day of handling.  Approach your hedgie quietly and slowly. Pick it up by lifting it from underneath, then hold it cupped in both hands.  Make time for play. As well as handling your hedgehog, don't be afraid to join in with play. Your hedgehog will accept your involvement in play if you join in regularly. Clean the dishes and water bottle/bowl daily with hot water. Clean the wheel and spot-clean daily, changing bedding weekly or as needed. Some hedgies are cleaner than others, so you may need to bathe it more or less frequently.  Fill a sink with warm (not hot) water to the level of the hog's belly. Water should not get in their ears or nose. Add a mild oatmeal bath (such as Aveeno) or puppy bath to the water, and use a toothbrush to brush out their quills and feet. Rinse with warm water and snuggle in a clean, dry towel until your friend is dry. If she'll tolerate it, use a hair dryer on low - otherwise, stick with the towel. Never put a wet hedgie back in its cage. If they get too long and curl around, they can get ripped off while running on their wheel.  Clip your hog's nails with small manicure scissors, trimming off only the very tips. If bleeding occurs, dab a little cornstarch on the spot with a Q-tip. Don't use commercially available powders, which are apt to sting. Quilling is the hedgehog equivalent of our losing baby teeth or a snake shedding its skin. This begins to happen at six to eight weeks of age and can happen throughout their first year of life as the baby quills make way for adult quills. This is a normal process and not something to worry about unless there are signs of illness or discomfort present, or the quills are failing to grow back. Your hedgehog may be irritable during this process and less amenable to being held; you can try an oatmeal bath to ease their discomfort. It is only a phase.
Keep the hedgehog in a quiet, peaceful space. Give the hedgie plenty of opportunity for exercise. Watch your hog's behavior and food/water intake. Handle your hedgehog frequently. Clean the hedgehog's home regularly. Bathe your hedgehog on an as-needed basis. Be sure to check your hedgehog's nails regularly. Be prepared for quilling.
