The Cuddly Catz program at the Larch Correctional Facility, a minimum-security prison is several months old, but inmates say they’ve already noticed a difference in the cats and themselves. The program began in cooperation with a local animal shelter. It has grown to include two cats and four inmates, and the prison plans to add four more cats. (AP Photo/Rick Bowmer)
