A closer look at the health of cats showing urinary house-soiling (periuria): a case-control study.

Objectives: The aim of this study was to perform a case-control medical evaluation of cats from multi-cat households presenting with inappropriate latrining and spraying behavior.

Methods: Owners of 18 'spraying' and 23 'latrining' cats with normal control subjects available from the same households were recruited for a case-control study. Otherwise overtly healthy dyads (each dyad consisting of a case cat and a control cat) were brought together to the veterinary hospital of the University of São Paulo for a medical work-up (ie, physical examination, complete blood count, biochemical profile, urinalysis and urine culture, abdominal ultrasound of the urinary system and in females, where possible, cystoscopy).

Age-based ultrasonographic criteria for diagnosis of autosomal dominant polycystic kidney disease in Persian cats.

Objectives: The aim of this study was to establish ultrasound criteria for the diagnosis of autosomal dominant polycystic kidney disease (ADPKD) in Persian cats.

Methods: Eighty-two Persian cats were assessed using renal ultrasound and genotyped for the C→A transversion in exon 29 of PKD1. The animals were also submitted to hematological characterization, serum biochemistry analyses and urinalysis.
