We just got our hedgehog a week or so ago and he is still a baby, about 9-10 weeks old. Right now he sleeps a lot. Whenever we take him out at night, his primary goal is to stick his head in some place dark and snooze. Some nights there is no evidence that he came out at all to eat or run on his wheel. He does always eat when we place him near his food bowl. Are adults this sleepy too? If not, when do they become more active at night?
