Like humans, cats have two (2) kidneys.
The kidneys
The structures that are retroperitoneal in a cat's urinary system are the kidneys, the ureters, and the urinary bladder. Retroperitoneal means that these structures can be found behind the peritoneum.
If the cat's ureter is obstructed, there is no place for the urine generated by the kidneys to go. As the pressure on the kidneys and bladder increases, one of two things could happen: some part of the system could rupture, causing internal bleeding, or the kidneys could fail, causing the cat to be poisoned by his own waste products.
Kidneys in cats are usually lower than in humans because humans are taller and walk upright.
