The Kat then began an on-screen rivalry with Terri Runnels, although neither were fully trained wrestlers. At WrestleMania 2000, Runnels (accompanied by The Fabulous Moolah) defeated The Kat (with Mae Young) in a catfight. Val Venis was the special guest referee, but he was distracted during the match when Young kissed him, which allowed Moolah to pull The Kat out of the ring. When Venis saw her out of the ring, he declared Runnels the winner. Post-match, The Kat attacked Runnels by stripping off her pants to expose her thong. The feud continued, and the duo had an arm wrestling match at Insurrextion. Carter was victorious, but after the match, Runnels pulled The Kat's top off, exposing her breasts, which Carter allowed instead of acting disgusted or embarrassed. The two women continued to feud throughout the summer, often in mixed tag matches. In June 2000, Carter attempted to regain the Women's Championship by entering a battle royal to become the #1 contender, but she was eliminated by her rival Terri. The feud resurfaced in a 'Thong Stink Face' match at SummerSlam, which The Kat won by performing a stinkface on Runnels.
