Feline lower urinary tract disease diagnosis in an obese sterile male Persian mixed-breed cat

Feline lower urinary tract disease (FLUTD) occurs because of dysfunction of the urinary bladder and urethra in cats. This study reported that FLUTD occurs in a castrated and obese male cat. The supporting diagnostics used to confirm the diagnosis are the dipstick test, urine microscopic observation, and ultrasound. The examination results showed pyuria, proteinuria, haematuria, struvite crystals, and cystitis. The pathophysiology of FLUTD in this case begins with the condition of castrated males, who tend to have little activity and become obese. Obesity increases the risk of ascending infections, which is one of the causes of crystal formation in the urinary tract.
