Guinea Pigs are so adorable. DO NOT hold newborn guinea pigs, if you do, the "human" smell rubs off on them. And if that happens, the mother doesn't care for them,and they don't help them out, like giving them milk, or sheltering them. If you hold a newborn guinea pig, their mother doesn't want anything to do with them. Also there is a chance that their mother will eat them, and yes, that could give you nightmares but this doesn't happen that often. If you want to hold a baby guinea pig, you have to wait a couple weeks (well, a month to be safe.)
