Ok so this movie is about a cat who goes on a catnip trip, that's where the name came from... get it? Cattrip? It's like catnip but trip instead of nip because he goes on a trip from the catnip. k
The movie plays at 40 fps, 166% faster than the normal 24 fps which is why the intro is much faster. Watch the whole movie, it ends before the lyrics start.
