Every hedgehog cage needs to have its own exercise space. A hedgehog that does not have space to exercise will quickly become bored and will start to have behavioural problems. In addition, a hedgehog that doesn't exercise will quickly become obese and this will shorten the lifespan of your hedgehog.
The exercise space does not have to be huge and you can provide exercise for your hedgehog out of the cate.
The main item that you should have in this area is an exercise wheel. When you choose a wheel, there are a few things you should consider:-
1. That it is a silent running wheel - Remember, the most active time for your hedgehog will be during the night so for your own rest, make sure the wheel won't squeak.
2. That it is solid - Although the solid wheels are usually more expensive, it is better to go with this since the wired wheels can pose a safety risk for hedgehogs. The solid wheels will keep them from falling through the bars and hurting their legs. In addition, make sure there are no sidebars on the wheel since they can cause injury when the hedgehog loos out the side of the wheel.
3. That it is the right size - Make sure that it is about 12 inches in diameter. While wheels that are smaller will work for young hedgehogs, anything smaller than 12 inches will be too small for an adult hedgehog.
4. That it is easy to clean - Like anything you put in the cage, make sure that it is easy to clean.
5. That it fits your cage - Lastly, make sure that it fits your hedgehog's cage. If it is too big, it won't give your hedgehog enough room to really enjoy his cage.
In addition to the actual wheel, you should have a few pet safe toys. The more things your hedgehog has to do, the happier they will be.
