The effect of duration of ownership and time spent together during the day on cat owners' level of understanding of cats' body language

Abdurrahman Köseman, Ibrahim Şeker, Abdulsamed Erez, Şenol Koşan

Published in 2024

Study revealing that cat owners do understand some of their cats' body postures, but with limited accuracy. Female graduates, aged 21 to 40, who spent 1 to 5 hours a day with their cats, were best able to understand the latters' body language. However,the study showed that having owned their cats for a long time and spent long periods of time together were not enough to ensure that owners correctly understood their cats' body language.

Published in 2024

Pilot study to investigate the effects of observer experience levels on pain assessments following pig castration in which observers with three experience levels  used the UPAPS scale to assess the animals.  Inexperienced observers showed lower agreement than experienced observers, although their predictive ability was similar.

Family pigs' and dogs' reactions to human emotional vocalizations:a citizen science study

Fanni Lehoczki, Paula Pérez Fraga, Attila Andics

Published in 2024

Scientific article on a study testing whether the emotional contagion provoked in dogs by human sounds of distress is the result of their selection for cooperation with humans or is rooted in the universal signals of emotion. The authors compared the reactions of dogs and pigs to recordings of human crying and humming. Dogs became agitated when listening to crying, which the authors interpret as emotional contagion, while pigs were stressed by humming, which the authors interpret as neophobia (fear of the new).
