Interactions with animals, including cats, is believed to influence human health. However, studies that investigate the psychological and physiological effects of interacting with cats in their household environment are limited. In this remote study, 32 cat owners in Japan participated from June to October 2021. They completed two tasks, each on separate days in their homes: one simulating daily cat communication (Interaction condition) and another with no interactions (Rest condition). We quantified emotions (arousal level and pleasure level) before and after each condition using the Two-Dimensional Mood Scale Short-term as well as salivary cortisol and oxytocin levels of owners using enzyme-linked immune-sorbent assay. Autonomic nervous activity (sympathetic and parasympathetic) was also quantified by heart rate variability analysis. The free interaction with cats decreased emotional arousal and parasympathetic activity, and lead to increased heart rates in owners. There was a positive correlation between heart rate and cortisol concentration, and between cortisol and oxytocin concentration. Furthermore, the frequency of petting the cats was negatively correlated with the rate of change in the parasympathetic activity. In contrast, the parasympathetic nerves in the owners were activated under the Rest condition. Hence, the mechanism of health-enhancing effects of cat ownership includes an arousing effect, in contrast to the previously proposed stress-reduction effect. This result can aid in future developments in cat–human relationship studies. However, a detailed study with a larger sample size is needed to draw definite conclusions.

<p>Microchips are a useful means for individual identification, and they are hoped to become popular for reuniting separated companion animals (dogs and cats) with their owners. However, pet owners’ views and thoughts regarding microchip mounting is not clear. This study aimed to reveal the predictors of behavioral intentions toward microchip mounting using questionnaires based on the Theory of Planned Behavior (TPB). The results revealed 306 valid responses [47.4% of owners (dog owners 51.7%, cat owners 42.1%, both owners 6.2%) and 52.6% of non-owners], in which 35 owners (28.4% of dogs and 8.8% of cats) had already mounted a microchip to their own pet. Pet owners scored significantly higher on subjective norms than non-owners on the TPB items. It was found that TPB explained the differences in attitudes between respondents and their use of microchips and their behavioral intentions for microchip adoption. Finally, this study also suggested that veterinarians would be the key to further dissemination of microchips.</p>
