Deb, I had guinea pigs when I was a kid. I prefer their personality much to that of a rabbit. Not sure I could eat them! My first "mid-wife" experience was with guinea pigs. My girl delivered 4 babies, and I found #4 buried in the shavings with the amniotic sac still intact. I picked the little guy up, peeled the sac back from his face, don't exactly remember what else I did to revive him, but I do know I prayed. Well, he came to life, and did just great. I named him Lucky. My understanding is that the South American "pigs" are much bigger than the pet quality pigs sold here in the states. I bet they are tasty!
Youtube has some videos about the South American ones.
