Rusty the Cat?? From Mission Impossible TV series, Episode "The Seal"
Taggert, a U.S. industrialist, has acquired a jade figure, which has great religious significance to Kuala Rokat. That nation is a small but strategically located nation which borders China. Taggert's acquisition threatens to undo years of sensitive U.S. diplomacy but there is no legal way to force him to give the figure back. Phelps devises a plan which, among other things, calls for causing havoc with Taggert's mainframe computer, Rollin impersonating an academic from Kuala Rokat and using a highly trained cat in getting the jade away from Taggert.
