What is your diagnosis?
Spike, a three-year-old, male neutered, domestic short hair cat, presented to Animal Kind Veterinary Hospital for straining to urinate. His person had noticed Spike making frequent, unsuccessful attempts to pass urine over the course of one day.
The veterinarian found that Spike’s urinary bladder was firm, distended, and painful on even light palpation. During examination he attempted to urinate but was unable to pass any urine. Temperature, pulse rate, respiratory rate, and the remainder of his physical exam were unremarkable. Stat laboratory tests demonstrated normal kidney function and electrolyte levels.
