But they're so cute.... All u needed to know about what I now have to do.

Ok so cooking Guinea pig appears to involve a big skewer.

From wikipedia...

Guinea pigs are a traditional food source in the Andes. Meals incorporating guinea pig are particularly associated with ceremonial occasions. Although the meat was for a time falling out of favour there has been a resurgence in its consumption. The most traditional Peruvian manner of cooking guinea pig involves building a stone pit and lining it with llama dung and firewood and then burying guinea pig carcasses in the coals once the fire has built up heat.
