I've done some research and compiled the best tips for you here based on my personal experience with Mr.Pokee. The adaptation process until your hedgehog will be tame consists of three main steps, that you need to follow:
Hedgehogs have very good noses and ears, however, very poor eyesight. Thus, in order to get your hedgehog accustomed to you, you should repeatedly confront it with your scent and your voice. Here are some examples:
Thanks to Pavlov we are familiar with the principle of Classical Conditioning. Pavlov's dog is the best known example: A dog gets food in conjunction with the blade of a bell. After a few repetitions only the simple sound of the bell activates the dog’s salivation. This principle can also be projected onto the hedgehog:
We can also spin the idea a little further: How can we unite this with our goal of getting a hedgehog used to us? This has worked with Mr.Pokee:
There’s nothing in the world that hedgehogs like better than mealworms. So, by linking the idea of reward with the classical conditioning, you're getting your hedgehog to unconsciously link the preservation of mealworms with your hand and your smell. You should repeat this several times to provoke positive associations.
Since your hedgehog has now accustomed to you and if you’re lucky even associates you with the reception of mealworms, you can now start to establish trust. Concerning this, I have two tips for you:
When you’re at that point and your hedgehog has become used to you and also trusts you, you can take the next step. You now slowly turn it upside down onto its back while it’s in your hand. Lay it down on something soft and slowly move your hand towards its belly. Let it sniff it, so it knows it is you and slowly start massaging its belly. Done! Your hedgehog is now tamed.
