Both resistive index (RI) and pulsatility index (PI) estimate vascular resistance within an artery. But, there are only few studies reporting normal values of the renal RI and PI in healthy cats but no study could be found with regard to Turkish Angora breed of cats. So, we decided to determine the normal values of intra-renal RI and PI in non-sedated, non-hypertensive clinically normal Turkish Angora breed cats. For this purpose 20 each of mixed-breed and Turkish Angora breed, different ages and sex healthy cats constituted the study groups. At the result of the pulsed wave doppler ultrasonographic examinations mean values for RI and PI were 0.61±0.04 and 0.97±0.17 for mixed-breed cats; 0.60±0.07 and 1.16±0.34 for Turkish Angora breed cats were recorded, respectively. No significant differences were noted between the groups. At the result, we determined that, they were in normal limits as previously described in clinically healthy Turkish Angora breed of cats.
