As a cage pet, hedgehogs require less care and attention than a dog or a cat. However, hedgehogs are still living creatures and require attention to their particular needs. When you consider a hedgehog as a pet, you are making a commitment that will typically last four to six years, and perhaps as long as ten years. You will be responsible for your pet's food, housing, medical care and exercise for a number of years, and you need to consider the investment carefully before making a hedgehog part of your household.
