Research overview: acoustic features of feline distress calls

Distress and high-arousal calls, such as the kitten separation cry and adult yowls, carry information about a cat's state and have been analyzed acoustically. This overview surveys research on the structure of these calls, including how kitten distress vocalizations elicit maternal retrieval and how adult high-intensity calls function in conflict, mating and confinement stress. It examines features like pitch, harshness and amplitude that may encode urgency, and parallels with the attention-grabbing properties found in the solicitation purr's embedded cry. The survey connects distress-call analysis to welfare monitoring and to understanding the emotional content of feline vocalizations, highlighting how acoustic measurement can reveal the intensity and possible meaning of sounds cats produce when frightened, separated or in conflict.
