In 1871 in York, Pennsylvania Stauffer's Biscuit Company was the first company to produce animal crackers. Other local bakeries soon came together under the National Biscuit Company, or "Nabisco." It was in 1902, that the animal cracker's box debuted with the "Barnum's Animals" circus theme.

So far there have been 37 different animals included in Barnum's Animal Crackers. The current crackers are bear, camel, crocodile, elephant, giraffe, gorilla, horse, lion, seal, tiger, and zebra.  More than 40 million packages of animal crackers are sold each year worldwide.

A box of Animal Crackers and a glass of milk a perfect way to celebrate National Animal Crackers Day.
