I never had a hedgehog as a pet but I crew up with them in Germany, We have quite a few over there, you could see the hole family at dawn going out for their nightly walk
When it became cold and too cold for the little ones, they had to be a certain weight to make it out in the wild, we where asked to take them in, so we had quite a few hedgehogs hibernate in the basement over the winter.
They are friendly little guys and will get used to people very quick...btw in Germany they are called "Igel"
Hope it helps a little
