  The oxytocin receptor gene (OXTR) polymorphism in cats (Felis catus) is associated with "Roughness" assessed by owners
■ 概要
  We examined the relationships between owner-assessed personality and oxytocin receptor gene polymorphisms in cats.We analyzed the exon1 region of OXTR in 94 DNA samples and found 3 single nucleotide polymorphisms. Questionnaires were completed by the cats' owners. Factor analysis for the scores identified 4 factors. A generalized linear mixed model analysis revealed that cats with the A allele in the single nucleotide polymorphism G738A showed significantly higher roughness scores than cats without the A allele. After dividing cats into 4 sex-neutering groups, only neutered females showed the significant difference between the A allele carriers and non-A allele carriers in roughness scores. Age also affected personality: younger cats showed much higher openness scores, whereas older cats showed higher roughness scores. This study shows that genetic variation in cats may be linked to their personality traits.
