I've been lucky enough to collect all four issues of the men's magazines that ran Stephen King's story The Cat From Hell and the associated contest winners: The original 500 words of the story, written by King (in the March 1977 Cavalier), the entire King story (Cavalier June 1977), and the two contest winners, Phil Bowie (Cavalier September 1977) and Mark Rains Gent (Gent December 1977).
I was asked to give synopses of the latter two stories in another forum, but I think this would be the more appropriate spot.
The following is from the September 1977 Cavalier that reviews the contest submissions and is the synopsis of the Rains story. I'll be following with the Bowie story synopsis soon.
