A wisecracking cat, Heathcliff knows he is the best cat around! When Heathcliff is not grabbing fish from the market or teasing Spike, he is full of love and good will for others, despite himself.
Heathcliff accidentally solves a Rubik's cubetype puzzle, so Iggy decides his cat must be a genius and submits him to a scientist for laboratory testing. Heathcliff doesn't blend well with the other animals, and in no time has managed to cause countless squabbles and sabotage all the lab tests./Cleo is bored with Westminster and asks Riff to take them to the exciting city. The cats build a giant balloon and fly it into the city. Once there, another gang quickly steals their balloon, leading to a chase across town.
