After more than a century behind bars, the beasts on boxes of animal crackers are roaming free. Mondelez International, which owns Nabisco, says it redesigned the packaging of its Barnum's Animals crackers after relenting to pressure from People for the Ethical Treatment of Animals. 

Nabisco has been making the animal-shaped cookies since 1902. The red-and-yellow packaging has always shown animals in cages, as if they're travelling in boxcars for the circus. 

PETA wrote to Mondelez in 2016, saying the box was outdated and should be changed. Mondelez agreed to a redesign. 

The new boxes feature a zebra, elephant, lion, giraffe and gorilla wandering side-by-side in a grassland.
