Usually I use Celebrity Sunday to post pictures of a celebrity's pet. This week, I decided to do things a little different, I wanted to feature what Kaley Cuoco of "The Big Band Theory" is doing for animals. Last fall Kaley broke her leg while horse back riding. While recovering in the hospital from her accident Kaley's boyfriend, Christopher French - lead singer of Annie Automatic, played guitar for her. Kaley began to sing along to "Somewhere Over the Rainbow." Kaley later decided to record and release the song on itunes to benefit the Humane Society of America. Check out the video below of Kaley encouraging people to adopt a shelter pet and singing her version of "Somewhere Over the Rainbow."
