Cassandra Cartland, otherwise known as She-Cat, grew up in the same orphanage as Selina Kyle, who would later on become Catwoman. Cartland had planned on stealing food for her fellow orphans, and had asked Selina if she'd like to help, Selina declined, not interested in working with other people. Cassandra attempted a second time to become friends with Selina after Selina had freed the orphans from their horrible orphanage. Selina once again, declined.
Later in life, when in adult-hood, Cassandra, still resentful after all these years, found out that Selina was Catwoman. How she discovered this is unknown, but she went through training, and soon became She-Cat. As She-Cat, she stole numerous items at Gotham's Museum, and all the blame was pointed on Catwoman.
She-Cat was created by Doug Moench and Jim Balent in Catwoman #42
She-Cat idolizes Selina internally and wants to replace her. She is similar to Selina in the fact that she is strong, independent, and sneaky in her dealings with others.
