M=male, F=female, y=years, w=weeks, HCT=haematocrit, USG=urine specific gravity, laboratory reference values in parentheses. Cat 12: not shown on above table is a DSH used as a control. Cats 1–11 were screened for PH (Table 3).
∗
Six months earlier had had clinical depression and azotaemia after jaw fracture (creatinine up to 1061 μmol/l).
– = Not examined, or data not available at the time of examination.
†
Euthanased at 6 weeks of age due to recurrent obstructive urolithiasis.
‡
A few renal epithelial cells observed in urine sediment.
§
Alive at the time of the testing for PH; euthanased 10 months later; renal histopathological examination available.
∥
Dead at the time of the study.
