Heathcliff and the Catillac Cats

Brain Sprain [Heathcliff] (1x33)

:

Heathcliff accidentally solves a Rubik's cube-type 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.
