SMALL INVISIBLE (part 6)

JD comes over to set up my new stationary bike (the bike peddles for you - it's geared for people with MS and Parkinson's). 

Before he leaves, JD corners the cat in the living-room and forces one pill down the cat's throat (an antioxidant). The cat moans. When JD leaves, the cat makes himself small and invisible beneath the air conditioning unit.
