The owner of Katzmer’s Curios, a small antique shop in Megakat City. He encountered Lenny Ringtail breaking and entering into his store, and informed him about the history of the Madkat Kat-in-the-Box. He also told Ringtail that it wasn’t for sale, but Ringtail overpowered Katzmer and took the relic, and transformed into Madkat. Later, Katzmer aided the SWAT Kats by telling them how to defeat Madkat: by destroying the three balls on his jester hat.
