I am pretty sure the "Krazy Kat' comic strip was super influential on the artists who came later - at least one (and I am pretty sure both) of Berkeley Breathed or Bill Watterson (both legitimate geniuses) was influenced by it. I don't know how many times I saw the animated show when I was growing up through the 70s, but it wasn't very often - we had "Top Cat" on our local independent channel, and it was great.
We also had "Heckle and Jeckle" on our other independent channel - in the mornings, it was "The Lone Ranger" at 6, then "Three Stooges," then "Looney Tunes," then "Heckle and Jeckle," then "Battle of the Planets" (literally the greatest thing in the world) and then something else, I don't remember what. For a while, "Rocky and Bullwinkle" was on then, and that made it the greatest 3-hour stretch of TV imaginable.
