The study included 99 cats, with a mean age of 8.0 AE 3.7 years and a mean body condition score of 4.6 AE 1.5 on a nine-point scale. The SBP ranged from 91 to 170 mmHg, with a mean of 116 AE 18 mmHg. Only two cats were hypertensive (SBP > 160 mmHg). Both had isosthenuric urine, were borderline proteinuric (UPC 0.2-0.4) and one of them was mildly azotemic. Mean sCreat was 101.7 AE 64.2 lmol/L (reference interval (RI) 44.2-141.4 lmol/L) and mean sUrea concentration 8.6 AE 5.2 mmol/L (RI 6.2-10.8 mmol/L). Thirteen cats showed increased sCreat levels, with decreased USG (< 1.035) in eight, proteinuria (UPC > 0.4) in seven and increased sUrea concentrations in ten of them. Five out of ten azotemic cats were proteinuric with a decreased USG. Mean UPC was 0.26 AE 1.06, with a wide range from 0.05 to 9.38. Borderline proteinuria was present in 40/99 (40.4%) and proteinuria in 28/99 (28.3%). Half of the proteinuric cats had a decreased USG. Mean USG was 1.040 AE 0.013. One third of all cats had a decreased USG, with isosthenuria in seven of them.
