when i was a kid i adopted an adult hedgehog who had not been very well socialised. Mostly, it was active at night, or when no one was watching it. OTher than that it slept, and waking it up was dangerous. They have razor sharp teeth, possibly in rows like sharks. They are covered in quills, and ball up painfully...i do remember that once it relaxed, and if i gave it some treats, and interacted with it when it was in a good mood, it was kind of social, and didn't always want to puff up or attack.
It had long, wet pellet type poop. Squishy more than hard, but still solid. I seem to remember that it had a natural oily scent, and it's piss could sometimes be really foul smelling.
My memories could be totally all made up. However, i'd advice you that hedgehogs are probably generally very similar, but their tameness and willingness to hang out depends on how much lovin' and good food the hedgehog has been exposed to. Kind of like a lover.
ohh my goodess but they are sooooooooooo cute! You have to read the wiki page. they do this awesome thing with salvia.
