We examined whether cats have a cross-modal representation of humans, using a cross-modal expectancy violation paradigm originally used with dogs by Adachi et al. (Anim Cogn 10:17-21, 2007). We compared cats living in houses and in cat cafes to assess the potential effect of postnatal experience. Cats were presented with the face of either their owner or a stranger on a laptop monitor after playing back the voice of one of two people calling the subject's name. In half of the trials the voice and face were of the same person (congruent condition) whereas in the other half of trials the stimuli did not match (incongruent condition). The cafe cats paid attention to the monitor longer in incongruent than congruent conditions, showing an expectancy violation. By contrast, house cats showed no similar tendency. These results show that at least cafe cats can predict their owner's face upon hearing the owner's voice, suggesting possession of cross-modal representation of at least one human. There may be a minimal kind or amount of postnatal experiences that lead to formation of a cross-modal representation of a specific person.
