Kidney disease is one of the most prevalent conditions in senior cats. Like us, cats are born with a finite number of kidney cells. The cells are not replaced when they die. Humans are born with about 1,000,000 kidney cells in each kidney.
Cats start life with just half of that, at about 500,000 per kidney, so it’s easy to see why they are so vulnerable to kidney disease. There is no cure, but if diagnosed early kidney disease can be managed very effectively.
