guinea pigs are not kosher
kosher requires
1. chew cud, ruminant.. and
2. split, cloven hooves
plus
as a rodent, guinea pigs would not be kosher even if they met the 1+2 test above.
Lev. 11 and Deut 14
So Pritzker couldn't eat a capybara either as a substitute for the baby pig.
Maybe a barrel of WhistlePig whiskey.
