"Hypersexuality" and Behavioral Changes in Cats Caused by Administration of p -Chlorophenylalanine

Abstract
The behavior of 26 male cats was systematically observed before, during, and after daily administration of the tryptophan hydroxylase inhibitor, p-chlorophenylalanine. These observations established that "hypersexuality," increased aggression, and perceptual disorientation are sequelae of the chronic administration of the drug in cats.
