CALISTA Approximately. DOB April 2017 DSH Calico, Female, Spayed Calista has been with Operation CatSnip since she was three weeks old. She was adopted once but her new mom was jealous of the bond between Calista and her new dad! Wow!! Calista, like many calicos, is sort of a 1 person cat but that person will not be disappointed in the love they receive in return for a warm home and loving friend.
