Kidney disease is a broad term that can include any time when the kidneys don’t function properly. This may be a long-term, chronic problem that slowly wears down the system over time, or it may occur suddenly.
What is kidney disease?
Kidneys filter blood. They filter metabolic waste products that are carried from the organs by blood to the kidneys and out of the body in the form of urine. When kidney disease develops, the tiny filters that do this may fail to do their job for any reason.

In chronic kidney disease, the kidneys gradually lose the ability to filter blood and make urine. As the kidneys struggle to maintain normal function, the metabolic waste that the kidneys are supposed to eliminate begins to accumulate in the blood. This buildup of waste products in the blood causes certain clinical symptoms that can make kidney disease life-threatening for cats.
