The infamous "Birdman of Alcatraz" isn't the only prison inmate to enjoy the company of an animal while serving time. Lots of prisoners participate in programs that give them contact with four (or two)-legged friends -- often to the benefit of both parties. Here are some of the most memorable animals living behind bars.
1. Dogs are an inmate's best friend.
There are lots of programs that connect prison inmates with dogs. One wildly successful example is at Gwinnett County Jail in Georgia, where dogs who would've otherwise been euthanized are matched with inmates so that they can be rehabilitated, trained and readied for adoption. Not only is it good for the dogs, inmates say it helps them grow more empathetic and enriches their lives.
