Actually, though, the Heinlein story probably is better known today because it inspired, consciously or otherwise, one of the most popular Star Trek episodes.
I understand your arguments, but still do not find them applicable to the quote. The relevant portion is "most fondly remembered of his 'juveniles.'" Other people, perhaps like myself, favorite STONES over Heinlein's other juveniles
for reasons that have absolutely nothing to do with tribbles' likeness to flat cats.
Granted, many people may have read "The Sentinel" and "Arena" for their association to better known works. Although I would say CHILDHOOD'S END was more of an inspiration to the subject matter of 2001 than "The Sentinel."
