Heathcliff and the catillac cats season 1 should only have 65 episodes. Each episodes have been split in two between healthcliff and then the catillac cats. The tvdb is wrong, which is what I believe trakt uses for TV shows. Tmdb and wiki are correct. Not sure if this can be fixed.
I believe the two shows played together and aired as one episode.
Please post the Trakt website link so we can take a look.
