Hoping to help Darrin locate an exotic model for his latest ad campaign, Samantha transforms a Siamese cat into a gorgeous girl named Ling-Ling (Greta Chi). Unfortunately, Ling-Ling wants to remain in human form, and to that end she begins using her feline wiles on Darrin's handsome photographer, Walter Ames (Jeremy Slate). Now that Sam has (literally) let the cat out of the bag, she has to figure out a way to straighten out the mess. Written by Jerry Davis, "Ling-Ling" originally aired on February 11, 1965. ~ Hal Erickson, Rovi
