My Ex-Gf was Peruvian, They call them "Cui" (read in spanish) or "coo-ee", because thats the sound they make when they "talk". also known here as guinea pigs. they are the same as the one's you get in Pet store, maybe a sligthly different since they are fed other foods.
They are easy to raise, keep them in a corral, throw veggetable leftovers, they eat any vegetable or leafy Veggie, roots like potatoes and carrots, and they have a special grass for them too.
She said her friend in Peru raised them to sell them to be eaten. Its not that difficult to find. I would eat it, I've also Eaten Rabbit. Rabbits are chewy.
Here near my house, they have an Asian market, they have geese eggs, and small chicken eggs with WITH THE PRE-CHICKEN FETUS inside, They also sell deep friend geese and Duck. they have Eels, Some weird looking fishes, And all sorts of Animal Organs for sale too, like Cow tongue and Bull Testicles.
