This is without a doubt the most convoluted episode of all the Perry Mason shows. To think a wealthy man would try to come up with a cadaver, then burn down his own mansion with all of his relative's possessions contained within only to test his heir's fidelity defies belief. How about trusting your own judgment? Submitted by PaulDrake 33, 7/24/2008.

Both “Caretaker’s Cat” and the previous episode “Jaded Joker” open with a piano tune. In “Jaded Joker,” Bobby Troup seems to be improvising a tune. In “Caretaker’s Cat,” Judy Lewis is playing a finished composition. I may have a tin ear, but it seems to me both these tunes are very similar. Perhaps, they are different parts of the same tune? Submitted by billp, 2/22/2009.
+ At the end of episode #57, Bobby Troup is credited with composing and performing the “Jaded Joker Theme.” It could well be the same tune played in the next episode, but there is no mention of it in the credits for episode #58. Submitted by gracep, 8/22/2010.

At two points during his examination of Nurse Devoe, Perry refers to an earlier conversation he had with her. This seems to have been edited out of the TV print I saw, though. I often wonder whether key clues have been edited out! Submitted by Ed Zoerner, 2/26/2011.
+ Indeed! I compared the DVD version of this show with one taped off the Hallmark Channel and found that the entire 1 minute 55 second scene where Perry talks with Ms. Devoe in her room is missing! I didn’t watch enough of the episode to know if there were any key clues, but there was a lot of talking. Submitted by daveb, 2/27/2011.

The burning of the house interposed with a cut of the burning of the newspaper announcing the millionaire’s is very dramatic and effective and well done. Submitted by gracenote, 4/18/2011.
