“The Cat People” is a 6-page Simon&Kirby horror story from Prize’s BLACK MAGIC #27 [Vol. 4 No. 3] .
George Gates goes to visit an old friend after a long time away in Europe, which ended in an extended hospital stay. He then freaks out when his friend’s kids are playing the string game cat’s cradle, and tells the story of his recent time in Spain, when he got lost and was invited to stay the night in the remote cavern home of an old woman and her beautiful daughter. As you’d gather from the title, they turn out to be able to transform into cats, using a spell cast by the original version of the cat’s cradle game. He barely escapes with his life, and not untouched.
A nice little story with an especially well done bit of adventure in the chase scene. The cat-like faces of the women are well done,
