Claims

Species: Cat (Felis catus)
Disorder: XX difference of sexual development, generic
Clin feat: De Lorenzi et al. (2017): "The cat possesses a tortoiseshell coat associated with male-like external genitalia, including normal scrotum with 2 palpably normal testicles. Histological analysis confirmed the presence of the testes, and cytogenetic and genetic analyses showed a female karyotype associated with the absence of the SRY gene"
