Chick-fil-A began celebrating Cow Appreciation Day in 2005 and participation has grown each year as the company has expanded across the country.
All you have to do is show up dressed like a cow (or any sort of cow apparel, really) and you'll get a free entree.
Get your cow costumes ready!
Free entrees for Cow Appreciation Day must be redeemed in the restaurant and can not be received through the Chick-fil-A app. A cow related t-shirt, hat or trousers will suffice.
It's all part of the fast-food chain's 15th annual Cow Appreciation Day.More news: Kevin Durant drops bombshell as free agency nears

The offer can also be used on breakfast items during breakfast hours.
The celebration runs from the time the restaurant opens through 7 p.m. Children in costume can receive a free breakfast entree during breakfast hours or a free kid's meal after.
Chick-fil-A has several restaurants in Southern California including locations in Ventura, Chino Hills, Torrance, Hollywood, City Of Industry, Downey, Newport Beach, Los Angeles, Norwalk, and more.
