Their names are Shadow, Butch, Misty, Rusty, Sparky, Sunshine, Esther, Marty and Spunky. They are cats, some former strays, some tiger-striped. But to Jan Fredericks of Wayne, N.J., they are family, they are God’s creatures and deserving of compassion.

And in Pope Benedict XVI, Ms. Fredericks, the chairwoman of the fledgling American branch of Catholic Concern for Animals, believes that she has found a kindred spirit: Along with an enormous entourage and a message of peace, the Pope brought with him to the United States a lifelong love of cats.

Benedict’s kindness toward the strays of Rome is already the stuff of Vatican legend. His house in Germany, its garden guarded by a cat statue, was filled with cats when Benedict lived there full time before he was posted to the Vatican in 1982.

And Benedict is, without a doubt, the first pope to have had an authorized biography of him written by a cat  Chico, a ginger tabby who lives across the road from Benedict’s old house in Germany.
