Pi Day is a fun holiday meant to celebrate the mathematical constant of Pi, or π. The event is observed each year on March 14, which is taken from the first three digits of Pi: 3.14.

Pi Day was actually recognized by the U.S. House of Representatives in 2009! Later, in 2019, UNESCO designated Pi Day as the International Day of Mathematics.

If you're a cat lover and you'd like to celebrate this math-themed holiday, why not pick up this silly mashup design featuring a cat with an eye patch, captioned with the word (PI)rate!

This wonderful book, Think Like a Cat: How to Raise a Well-Adjusted Cat--Not a Sour Puss, is a sort of guide to raising and living with companion cats. I read this book years ago when we first added cats to our family and it helped us to understand the minds of our little furry companions.

The guide covers topics including understanding cat communication, training your cat, keeping your cat safe and healthy at home, and problem-solving. Our favorite chapter is subtitled "Yes, You Can Have a Cat and Nice Furniture Too".
