In South America, which rodent is considered a delicacy?

I could never eat my pet guinea piggies!!!!

Ate it in Peru where they often run wild around the house prior to becoming dinner. I don’t think they are eaten all over South America, however.

Paul Steadman, I don't understand why that reference is there as there is no other mention of liver in the explanation.

Love the Hannibal Lecter reference in the description.
