Isis is one of Selina Kyle's pet cats and a frequent cohort and accompaniment in her nightly escapades.
One of her more favored pets, Isis has been trained by Catwoman to be her diminutive partner in crime. To this end, on top of conventional tricks of item retrieval and following commands, Isis has learned to detect, and evade laser based security systems, is capable of identifying and shutting down lever/switch based obstacles and retrieve priceless jewels and artifacts for her owner on her own. Isis is also capable of sneaking up to and attacking opponents that impede her or her owner's way.
