2. Kidney Disease Signs May Take Time to Become Visible
Kidneys are made up of microscopic nephrons. As your cat ages or if the kidneys become damaged, some nephrons begin to die and other reserve (or "resting") nephrons take over. Once there are no extra nephrons remaining, your cat may begin to display signs of kidney damage such as loss of appetite, weight loss, increased thirst, and anemia. However, this often only occurs once 75% of kidney function (2/3 of nephrons) has been lost. This is why it so important you bring your cat to veterinarian at least once a year and remain vigilant for unusual signs in your cat's behavior. It may help prevent your cat from developing kidney disease in the first place.
