Research overview: frequency discrimination in cats

Beyond detecting sounds, cats can discriminate between tones of different pitch, a capacity studied through behavioral and physiological methods. This overview surveys feline frequency discrimination, examining how finely cats can tell apart neighboring frequencies across their broad hearing range. Such discrimination supports the recognition of meaningful prey and conspecific sounds amid background noise. The survey relates discrimination performance to cochlear tonotopy and central auditory processing, drawing on the cat's role as a classic model in hearing research. It discusses how discrimination ability varies across the frequency range and how it complements the cat's strong sound-localization skills. Characterizing frequency discrimination rounds out the picture of feline hearing beyond mere range and sensitivity, showing that cats not only detect a wide band of sounds but can also parse them into distinct pitches, an ability useful for distinguishing the subtle acoustic signatures of prey, threats, and other cats.
