Kaitlyn Karkoska cuddles with "Brad Pitt," a black cat up for adoption, during "The Book Buddies Program" at the Animal Rescue League of Berks County in Birdsboro, Pennsylvania February 11, 2014. Children in grades 1-8 read to the cats as a way to improve their reading skills and gain confidence. The shelter animals can be a non-evaluative presence that can provide support and comfort to participants without judging them. Students showed sustained focus and maintained a higher state of awareness, as well as improved attitudes toward school, according to researchers at Tufts University. Photo taken February 11, 2014.
