On the DVDs, the black and white episodes have a grayscale version of the MCMLXVI opening. There is no CPT holdings credit.

The reruns you see with this credit are actually the colorized episodes--with the color turned off!!

There are 3 major versions of the opening theme.

B&W with a caricature of Dick York
Color with a caricature of Dick York
Color with a caricature of Dick Seargent.

I never did see an episode where Sam turns herself into a cat, though in one episode Darren thought she did, and Sam later turned that same cat into a woman. In that same episode, Endora really did turn herself into a pelican.
