Fifty cats with signs of lower urinary tract disease (hematuria, dysuria, pollakiuria or urethral obstruction) were studied as far as clinical, laboratory and radiographic abnormalities were concerned. These animals were distributed in two groups, the first one comprised thirty-six male cats with urethral obstruction and the second, fourteen male and female cats presenting hematuria, dysuria and/or pollakiuria. Another group of twenty-five healthy cats, both sexes, different ages and breeds, fed exclusively with commercial dried food was included as control. Serum urea and creatinine measurements, urine analysis, urine culture and excretory urography were performed in all cats. The results showed that urinary tract infection was rarely seen. No significant difference was detected between castrated or intact animals. Among the sick cats the most consistent abnormalities found were: urinary alkaline pH, crystalluria and thickness of the urinary bladder wall. The difference in urine pH observed among healthy and sick animals fed with the same kind of meal should be stressed and deserves further studies.
