Zvi Bar-Kochba has been blessed with several polite cage-free guinea pigs as pets.This can be seen in the June 26 video uploaded to Instagram that shows the courteous rodents waiting in line for their owner to give them a carrot stick.Once the guinea pigs took their treat, they scuttled “to a place where they can really pig out,” Zvi told Storyful.
