They climb, dig, swim, and often go for night runs for miles on end.
Make sure your cage has enough space for an exercise wheel and a hiding spot for your hedgehog to sneak away and sleep in.
Otherwise it will keep you up all night running on its wheel or playing with its toys.
Without enough time to run around in and outside of their enclosure, your hedgehog is at risk of becoming overweight.
If you are checking/testing to see if your hedgehog will drink from a bottle, be sure to include a water bowl in the enclosure during this trial period until you are certain they are drinking from the bottle.
After hedgehog-proofing your place, give your buddy time to run around outside of the enclosure.
Because of this, your hedgehog’s enclosure must be big enough to enable their natural behavior.
The exercise wheel is a very important piece of maintaining your hedgehog’s health.
The lifestyle of a nocturnal pet may mean that you’ll want to keep your hedgehog’s enclosure away from your bedroom, especially if you are sensitive to noise.
Sadly, many hedgehogs who are kept as pets are fed a diet too high in fat and don't get enough exercise, which can cause obesity and other health problems.
Make sure the wheel is solid, and not made of wire; their feet can get stuck in the wires and this may cause fractured limbs.
Liver disease and obesity often occur because of unhealthy eating habits, an unbalanced diet, and minimal exercise.
