lol my bro raises those damn things. They are kinda crazy if they don't know you. They really kind of Tuck into a ball if their scared... sorta like Sonic.. lol.. their kinda cool but I don't know why the hell you would want one for a pet... but then again.. there is a lot of people who have some other fucked up pets.. Oh and they really are not mean. They can bite you but they are so small its nothing to really worry about. Their spikes are sharp as hell too. Hard to even pick them up.. again not sure why you would one as a pet but people love them.
honest to god i cant even believe u said that.
porcupines are rodents and hedgehogs are insectavores. there only similarity is superficial. sorry to burst ur bubble on that one buddy
