Preview: In contemporary western cultures, most humans talk to their pet companions. Speech register addressed to companion animals shares common features with speech addressed to young children, which are distinct from the typical adult-directed speech (ADS). The way dogs respond to dog-directed speech (DDS) has raised scientists' interest. In contrast, much less is known about how cats perceive and respond to cat-directed speech (CDS). The primary aim of this study was to evaluate whether cats are more responsive to CDS than ADS. Secondarily, we seek to examine if the cats' responses to human vocal stimuli would differ when it was elicited by their owner or by a stranger. We performed playback experiments and tested a cohort of 16 companion cats in a habituation-dishabituation paradigm, which allows for the measurement of subjects' reactions without extensive training. Here, we report new findings that cats can discriminate speech specifically addressed to them from speech addressed to adult humans, when sentences are uttered by their owners. When hearing sentences uttered by strangers, cats did not appear to discriminate between ADS and CDS. These findings bring a new dimension to the consideration of human-cat relationship, as they imply the development of a particular communication into human-cat dyads, that relies upon experience. We discuss these new findings in the light of recent literature investigating cats' sociocognitive abilities and human-cat attachment. Our results highlight the importance of one-to-one relationships for cats, reinforcing recent literature regarding the ability for cats and humans to form strong bonds.
