My wife had one, when we firsat met..
she says:
Ahh... get them when they are young, and handle them a lot.. If you're squeemish about the spines / quills, then don't bother. They love to eat meal worms and king worms (some grub type bug things) but it is good to feed them dry 'low cal' cat food. I also made a excersise wheel for them, by modifying a 'rat' wheel, covering the 'running surface' with fine grit sand paper (keeps the toes nails short). They need the surface, as they will put their feet though the bars. You'll have to change the paper often, as they, uhm , pooh, as they run. watch long / loose hairs as mine got some of my hair wrapped around a toe, and it got infected.. They grunt and huff & puff a lot.. (it's their 'happy sound') If you are worried about socialization, they are fine on their own, but socialize with it a lot to get it to know you. And, remember, they are nocturnal, so they'll be more active at night.. I didn't have any previous experience with mine, when I first got him, and I was weary about handeling him, which I regret. I find them interesting animals but I probably wouldn't get another one in the future.
