Abstract

Background:
Cat urolithiasis is more common in male orchiectomized cats.

Aim:
This study aimed to determine the effect of orchiectomy on productive performance, physiologic, hematologic, and blood chemistry parameters, renal function, and electrolyte handling in healthy adult cats.

Methods:
Ten male, 2-3 years old, 4.7-5.9 kilograms, with a moderate body condition score (BCS), and clinically healthy domestic cats were used in this study. The animals were divided into two groups: the ORCH group and the SOC group. Before surgery, daily weight gain, food intake, water intake, and urine volume were recorded, and urine pH and urine ammonia excretion were measured. Furthermore, vital signs, urine specific gravity, and UPCR were measured, and clearance studies were conducted. The biological, clinical, and renal function parameters were measured 5 weeks after surgery, as they were before surgery.

Results:
Orchiectomy in adult male cats increased productive performance (weight gain and food intake) without altering physiologic, hematologic, and metabolic parameters. The serum testosterone concentration in orchiectomized animals was significantly lower than that in the SOC group (P
