Meet the pampered piglet that lives a life of luxury - demanding belly rubs, building pillow forts and eating CHEERIOS. Sarah Kocher, 20, rescued pot-bellied Petunia after she was abandoned by her original owner. Now the house-trained hog lives at Sarah's house with her family and their other pets - two pugs, a Labrador, a cat, tortoise and chicken. According to Sarah, one-year-old Petunia - affectionately nicknamed ‘Tuna’ - rules the roost.
