Does Captivity Affect the Size of a Hedgehog?

Hedgehogs are solitary animals that prefer to be alone. A wild hedgehog can walk around and be alone when it needs to be. Domesticated hedgehogs are often kept in captivity, which makes people wonder if it stunts their growth.

However, this is not true.

Being held in captivity does not affect the size of a hedgehog. What matters the most when it comes to how big a hedgehog will be is its breed. Domesticated breeds grow to be smaller than wild hedgehogs because they have been bred this way purposely.

People prefer to house small ones as compared to big ones because they take less space. Since hedgies like to explore and cover a lot of ground in the wild, a small hedgehog is preferred.

Big hedgehogs will take more space and require more area to explore. You will need a big cage for a big hedgehog.  Failure to provide a hedgehog with ample space can lead to becoming depressed and other issues such as losing its appetite.

Hence, as a result, small breeds are bred to avoid this problem. Small hedgies make better pets than big ones.

Any that belong to small breeds are generally smaller in size than other breeds, even in the wild. This shows that the main factor contributing to their size is its breed rather than being held in captivity.

Can Hedgehogs Have Weight Problems?

Hedgehogs in the wild are constantly on the run during nighttime when they explore, search for food, or mate. Hence, wild hedgehogs get a lot of exercise.

The small size of the hedgehog makes it more prone to weight gain. This means that if your hedgehog is not burning enough calories, it can take the road to obesity. Obesity in hedgehogs can lead to health issues and shorten their lifespan.

This problem is prevalent in many domesticated hedgehogs. Hence, you should ensure that your hedgehog has a lot of space to run in its cage and has a wheel. If you feel your hedgehog weighs too much, consult your vet.
