little Hedgehog

When I was a child, my father worked at a train station in the suburbs. There would often be hedgehogs outside the train station. The next day, my father would bring one or two hedgehogs back when he got off work. At that time, he used bricks to form a circular nest for fear that it would escape. When he moved it, it would shrink into a ball and roll into a ball. Its eyes looked like mice. It would feed him, cabbage and radishes. It would not eat it for fear that it would starve to death, so it would let it go every night. I didn't know where it would crawl and enter an unfamiliar environment. Will it be uncomfortable? I was very sentimental at the time, but now I see a hedgehog is especially cordial.
