 The reasons for the cancellation of SWAT Kats are unknown. SWAT Kats  was doing very well in the ratings. Due to high ratings between  August 30, 1993 and April 17, 1994, SWAT Kats became #1 new  syndicated cartoon of 1994 . The rating results were approved by  Nielsen Television Index (NTI) and Nielsen Syndication Service.  Hanna Barbera Productions promised fans that they are going to  release more episodes in 1995. And they even released a full page ad  in October/November (1994)issue of Animation Magazine. But that  never happened to this successful show. Turner Program Services  ordered to cancel the show, while they were finishing Second Season.  Christian Tremblay and Yvon Tremblay (Creators of SWAT Kats) became  surprised when they heard about the cancellation of the show,  because the show was doing really well in the ratings. Many fans  sent letters to Hanna Barbera Productions about this subject. But  Hanna Barbera Productions didnt replied to their letters probably  because of the financial disaster they had with Jonny Quest Real  Adventures.
