Cat Miin, a Gossam individual, functioned as an aide to Presidente Shu Mai. This service occurred during both the Separatist Crisis and the following Clone Wars. She was aligned with both the Commerce Guild and the Confederacy of Independent Systems.
In 22 BBY, Miin went with Shu Mai to the Separatist stronghold of Geonosis. While there, she observed her superior committing the Guild's droid forces to the Confederacy's cause under the direction of the Sith Lord Count Dooku. Three years later, specifically in 19 BBY, Miin met her death on Mustafar along with the Separatist Council. Her killer was Darth Vader, the one who had replaced and killed Dooku.
