Urolithiasis, kidney failure, urinary tract infections are examples of disorders of the urinary tract that often become problems in cats. Urolithiasis is a medical term to describe the presence of stones or crystals known as “urolith” in the urinary tract. Inappropriate composition and feeding methods can cause nutritional imbalances in the cat's body, which can affect the acidity level (pH) of urine, urine volume and urine concentration which can cause the formation of excessive minerals in the urine. The aim of writing this article is to provide information regarding the treatment of crystal urolithiasis in local cats. A male cat named Goblin, has been castrated, has colored hair orange with body weight 5.3 kg, experiencing difficulty urinating since 3 weeks, excreting a small volume of urine, and blood in the urine.

Ultrasound results showed enlargement of the left kidney and deposits of hyperechoic particles (crystals) accompanied by enlargement of the uterine sac. The cat was diagnosed with urolithiasis with a fausta prognosis. The cat was treated by installing a 4Fr/1.3x130mm urinary catheter and flushing using 0.9% physiological NaCl to make it easier for the cat to urinate. The therapy given is the antibiotic ciprofloxacin hcl 5 mg/kg BW s500 mg preparation with a dose of 50 mg/kg BW per oral (PO) administered 2 times a day for seven days, administering the anti-inflammatory dexamethasone 0.5 mg with a dose of 1 mg/kg BW PO and given 2 times a day for four days, and kejibeling herbal medicine 1 tablet times a day for seven days.
