To evaluate kidney function, veterinarians will most often turn to blood tests and urine analysis (urinalysis) to evaluate the concentrations of waste products and other components that healthy kidneys normally filter or regulate.
Why do cats have lethargy?
Another cause of lethargy in cats with CKD is the buildup of acids in their blood. The kidneys of cats with CKD may not excrete these compounds appropriately, making affected cats prone to blood acidification, or acidosis, a condition that can significantly affect the function of a variety of organ systems in the body.

Overview
Kidneys filter toxic waste products from the blood into the urine so that your cat can pee them away. If the kidneys aren’t working properly, waste products build up and cause illness. There are two types of kidney disease, ‘acute’ and ‘chronic’. This article focuses on chronic kidney disease (CKD).

Causes of chronic kidney disease
Many cats develop kidney disease when they reach their senior years (8+) due to wear and tear on the kidneys throughout life.
How will kidney disease affect my cat?
The kidneys make sure the right amount of water stays in your cat’s body. Diseased kidneys don’t retain water, so cats with CKD drink and pee much more than usual.

Not eating?
If a cat with kidney disease stops eating, they are at risk of becoming even more poorly. It’s better that they eat something rather than nothing.
What is a cat's kidney disease?
If the kidneys are not functioning normally for more than three months, it is referred to as ‘Chronic’ Kidney disease (CKD).

1. High urea and creatinine levels
If the cat’s creatinine and urea levels are over 7.0 mg/dl and 150 mg/dl respectively, the end could be near. These numbers occur during the end-stage of the disease and rarely drop even after undergoing treatment.
2. Reduced urination & inability to urinate
While cats suffering from chronic kidney disease tend to urinate profusely, this changes once the condition is advanced. The cat will produce less and less urine over time, and the worst case is when they cannot urinate at all.
3. Bowel and bladder incontinence
Instead of experiencing reduced urination and an inability to urinate, some cats develop the opposite once the condition is advanced. The cat will urinate and/or poop wherever they are lying due to the inability to control bowel and bladder movements.
4. Extreme weight loss
Weight loss is common in older cats due to loss of muscle mass as a result of the body’s reduced efficiency in digesting and building proteins. A cat suffering from chronic kidney disease can get extremely thin to the extent the ribs, spine, and hip bones protrude under the skin.
5. Not eating or drinking
If your cat is suffering from kidney failure and reaches a point where they refuse to eat or drink, you should be concerned. Failure to eat or drink will lead to lethargy, dehydration, and weight loss.
6. Congestive heart failure
Another sign a cat is dying of kidney failure is having heart problems such as congestive heart failure. It’s a condition where fluids leak out of the veins and build up in the lungs, around the lungs, or in the abdomen. If the fluids are not drained off, the cat will eventually drown from the fluids in the lungs.
7. Bad breath and body odor
Most cats with chronic kidney disease have bad breath that smells like ammonia. This gets worse as the condition advances. While it’s possible to treat bad breath, it will only get worse and worse as toxin levels in the cat’s body increase.

Function
- The kidneys are part of the renal system (Figure 1), the bodys system for filtering impurities out of the blood. Urine produced in the kidneys is carried to the bladder by the ureters and from the urinary bladder to the outside world by the urethra.
Symptoms
- Clinical Signs Cats with CKD may experience a buildup of the waste products and other compounds in the bloodstream that are normally removed or regulated by the kidneys. This accumulation may make them feel ill and appear lethargic, unkempt, and lose weight. They may also lose the ability to concentrate their urine appropriately, and as a result they may urinate gre…

Therapy is geared toward minimizing the buildup of toxic waste products in the bloodstream, maintaining adequate hydration, addressing disturbances in electrolyte concentration, supporting appropriate nutrition, controlling blood pressure, and slowi…
Prognosis
- Prognosis Some cats respond very well to treatment for CKD while others do not, so the prognosis for CKD in affected cats is quite variable. Some studies suggest that cats that lose more protein in their urine have less favorable prognoses. There is evidence suggesting that the earlier CKD is diagnosed and treatment is initiated, the better the ou...
