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.
We use TVDB and it looks to match up with the order they have.
I believe the two shows played together and aired as one episode.
Please post the Trakt website link so we can take a look.
