As with all PD MGM feature-length films produced by the studio itself (and possibly a few they merely distributed), the original film elements are now owned by Turner Entertainment, with distribution rights handled by Warner Bros. (who spoofed the title in one of their 1954 short subject cartoons, Claws for Alarm).
This short was edited into Daffy Duck's Quackbusters (1988), and is featured in its entirety in the Looney Tunes Golden Collection: Volume 3.
It was the first of three Jones cartoons which placed Porky Pig and Sylvester the cat (in a rare non-speaking role as Porky's pet) in a spooky setting where only Sylvester was aware of the danger - the other two films being Claws for Alarm (1954) and Jumpin' Jupiter (1955).

Porky and Sylvester would later be paired in a trio of shorts directed by Chuck Jones: Scaredy Cat, Claws for Alarm, and Jumpin' Jupiter.
