Breed differences in social behaviour in logistic regression analyses. The letterings indicate groups (false discovery rate corrected P > 0.5 between breeds within the same group) that significantly differ (FDR corrected P < 0.05 between breeds in different groups) from other breed groups. Turkish Van cats were the most aggressive towards family members (a), strangers (b), and other cats (c). Russian Blue cats had the highest probability for shyness towards strangers (d), and British Shorthair cats had the highest probability for decreased contact to people (e). Error bars indicate 95% confidence limits. N = 5726.
