Cats are neat planes!  About 25 years ago an "exec conversion" Cat was at my local airport in New Bedford, MA (EWB for those who speak pilot). It had comfy swivel leather seats in both of the observation/gunner's bubbles as well as a nice interior with galley, bar, etc. It had a wonderful two toned blue paint job.
 
About 12 years ago Jimmy Buffett's Cat "Hemisphere Dancer" was open to the public at the Rhode Island Air Show. Nice practical interior, and one hell of a way to transport one's surfboards and fishing gear. In one of his books he writes about dropping down onto the water, popping open the upper part of the rear hatch and tossing in a line. The Hemisphere Dancer is now on display at Buffet's Margaritaville in Orlando. A rather ignominious way to spend ones days...
