Good observations RA.  I have some "Inside Baseball" knowledge on this one.  The series Katts & Dog, had an executive producer named Herbert B. Leonard.  I knew Mr. Leonard personally.  Due to Canadian tax shelter and Cancon certification, Mr. Leonard was listed only as "Executive Producer".  But that's not quite accurate. He had a much larger role on that show.  If you search IMDB you will find that Bert Leonard was a producer of Rin Tin Tin back as far as 1955. There were several Rin Tin Tin sequels over the decades.  Bert also produced Route 66, The Naked City and many other TV series during the "golden age" of TV Drama.  Mr. Leonard's exit from Canadian television is a rather sad story that I won't recount here. But he was the "real deal" in terms of legendary TV producers.,  I worked with him for a few years.  While working with him in LA, I had breakfast at the St. James Club in LA, and I asked him about some of his casting "regrets".  I seem to recall that he passed on Dustin Hoffman, when casting Route 66.  He also was a big fan of "Leonardo"..who was not a household name at that time. I awkwardly asked "Leonardo who???" He explained to me the actor was Leonard Di Caprio - who was a relatively young teen at the time.
