Mittens is the deuteragonist of Disney's 2008 animated feature film Bolt. She is a sassy and short-tempered street cat whom Bolt at first mistakenly believed was an agent of Dr. Calico. She is pessimistic and has a dry sense of humor. She lives the life of a thief who suffers from traumatophobia (a fear of battle and physical injury). She wasn't interested in friendship at first but she is eventually moved by Bolt's loyalty and willing to know about how to live a normal dog life. Judging by her color patterns, she appears to be a Tuxedo cat who speaks with a New York accent.
