Isis is Catwoman's pet house cat.
History[]
Catwoman is shown to keep many cats, among those is her favorite cat, Isis. One addition to the mythos was giving Catwoman a pet black cat named Isis, who appears in the Batman the Animated Series and in The New Batman Adventures. She first appears in the episode The Cat and the Claw Part I around Catwoman's neck as she was climbing a building to rob the penthouse. Upon first meeting Batman, Isis hisses. As Catwoman's cat, she fights the dogs of Superman and Batman, as well as Streaky the Supercat, on Krypto the Superdog, a cartoon made by the same people who made the DCAU. Isis also appears briefly in The Batman.
History (Krypto the Superdog)[]
In the animated cartoon series called Krypto the Superdog, Isis is a recurring foe of Krypto, Streaky the Supercat and Ace the Bat-Hound. She's depicted as a Siamese rather than a black cat.
