We just happened to find this picture online today, two hedgehogs side by side in a human hand. So cute! One is still a baby, sporting newly grown spikes, while the other is larger (not as large as a hedgehog can get!). Hedgehogs are not aggressive, but rather passive and they suffer a lot when their spikes are growing. If you have a hedgehog pet, you should rub his skin with some vegetal oil (like sunflower or olive) to keep it most and soft while the spikes are appearing. He’ll appreciate it!
