Happy Pi Day! In case you’re not as nerdy as I am, today is a day to celebrate pi — the ratio of a circle’s circumference to its diameter. It’s a never ending number that starts 3.14159. Reciting it was a game of sorts in a high school math class. Today, March 14, is a day to celebrate the beauty of mathematics by eating pie, playing math games — and sharing adorable adoptable pets who want to celebrate in a new home!
