Study Reveals Behavioral Differences Among Cat Breeds

Researchers from the University of Helsinki analyzed data from about 5,726 cats to identify behavioral patterns and assess the heritability of traits. The findings indicated significant behavioral differences among the breeds, with around half of the observed traits—such as activity level, shyness, aggression, and sociability with humans—being inherited.

The most prominent differences were related to activity levels, while the least variation was found in stereotypical behaviors, which include repetitive actions like pacing or paw chewing. Hannes Lohi, study co-author and lead researcher, noted that activity is a relatively stable trait established by about two weeks of age, whereas environmental factors significantly influence stereotypical behavior.

The researchers concentrated on Maine Coons, Ragdolls, and Turkish Vans to estimate the heritability of their behaviors. The study drew on behavior questionnaire responses from almost 6,000 cats spanning 40 different breeds. The selected breeds were noted for their genetic diversity, with Maine Coons linked to Nordic breeds, Ragdolls to Western European and American varieties, and Turkish Vans having distinct historical origins.

The study revealed that Ragdoll cats tended to be shy around strangers and displayed aggression towards humans, while Turkish Vans showed aggression towards both humans and other cats. Approximately half of the differences in breed behavior could be traced back to genetic factors, although some behaviors may have been influenced by selective breeding practices.

Future research aims to include a broader sample of around 20,000 cats to further investigate the intersection of genetics and environment in feline behavior. Initial findings from the study highlighted various interesting behaviors across breeds; for instance, British Shorthairs showed a high tendency for reduced human interaction, while Russian Blues were often shy with strangers.

The authors concluded that the traits under study are moderately to highly heritable, suggesting that breeding programs focusing on personality traits could lead to improved welfare outcomes for cats.
