If your cat is less active and drinks more, he or she may be suffering from chronic kidney failure (CKD).
This is a serious condition that requires immediate attention to improve the quality of life of your beloved pet.
Treatment of CKD in cats includes special diets, medications to treat complications, and supportive measures such as fluid therapy.
In this blog, you will learn all about the causes, symptoms, diagnostic methods and treatment options for cats with CKD to help your four-legged friend live a longer, healthier life.
Causes of Kidney Failure in Cats

The causes of kidney failure in cats are varied and can include both genetic and environmental factors. The most common triggers include poisoning by substances such as antifreeze, pesticides and certain plants such as lilies. These toxins can cause serious damage to the kidney tissue, impairing kidney function.
In addition to external toxins, various diseases such as infections, systemic diseases such as diabetes or autoimmune diseases and congenital conditions such as polycystic kidney disease can also contribute to the development of renal insufficiency. Age-related degeneration of the kidneys also plays a significant role, especially in older cats.
Other risk factors include long-term use of certain medications that can put strain on the kidneys and nutritional deficiencies, such as too much phosphorus in the feed. Knowing these causes is crucial to taking preventative measures and maintaining kidney health for as long as possible.
Recognizing symptoms of kidney failure

Symptoms of kidney failure in cats are often subtle and only become apparent in advanced stages. Early signs include increased drinking and urination, weight loss, and a general reduction in activity. These changes can be easily overlooked, so it is important to pay attention to such subtle clues.
Other symptoms include loss of appetite, vomiting, bad breath, and a dull and shaggy coat. In advanced cases, dehydration, mouth ulcers, or neurological symptoms may occur. These clinical signs reflect the accumulation of toxins in the blood that would normally be excreted by healthy kidneys.
Diagnostic Methods of Renal Insufficiency in Cats

Diagnosis of renal failure in cats typically begins with a thorough history and physical examination, followed by blood and urine tests. These tests measure blood levels of creatinine and urea, which are elevated in renal failure, as well as other important markers such as SDMA, which is specific to kidney function.
In addition to laboratory tests, the veterinarian may perform an ultrasound of the kidneys to identify structural changes such as enlargement, reduction, or stones. These imaging tests are crucial to assess the extent of damage and plan the best possible treatment.
In some cases, more specific tests such as a biopsy of the kidney tissue may also be required to determine the exact cause of the kidney failure. Early diagnosis through these different methods is crucial to slow the progression of the disease and improve the quality of life of affected cats.
Treatment options for renal insufficiency
There are various approaches to treating renal failure in cats that aim to improve the animals' quality of life and slow the progression of the disease. Treatment options vary depending on the severity of the disease and can range from simple dietary adjustments to drug therapies. It is important that each therapy is individually tailored to the needs and health status of the individual cat in order to achieve optimal results.
Drug therapies play a central role in treating symptoms associated with renal insufficiency such as high blood pressure and anemia. These medications help regulate blood pressure and promote red blood cell production, which in turn supports the cat's overall health and well-being. In addition, phosphate binders are often used to reduce phosphate absorption in the intestines and thus relieve the strain on the kidneys.
In addition to drug treatment, fluid therapy is an important supportive measure, especially in cats prone to dehydration. This therapy can be administered either subcutaneously at home or intravenously in a veterinary clinic. The aim is to ensure adequate hydration and promote the elimination of toxins that would otherwise accumulate in the bloodstream.
Nutritional Management in Cats with Kidney Disease

An adapted diet is crucial for the treatment of cats with renal insufficiency. Special kidney food that is low in phosphorus and protein, but rich in essential fatty acids and potassium, can help to reduce the load on the kidneys and minimize the formation of urinary substances. It is important that the diet change is carried out gradually in order to increase the cat's acceptance of the food.
In addition to adjusting main meals, drinking habits can be encouraged by various measures, such as offering fresh water at several locations or adding meat juice to the water. Adequate fluid intake is essential to support the kidneys in eliminating toxins and to minimize the risk of dehydration.
Prognosis for cats with renal insufficiency
The prognosis for cats with renal insufficiency depends largely on the stage of the disease at diagnosis and subsequent treatment. Cases that are detected early can often still have a good quality of life and a longer lifespan with appropriate therapy. Regular veterinary check-ups are therefore essential to monitor the cat's health and adjust the therapy if necessary.
In advanced stages of renal failure, when kidney function is severely impaired, life expectancy can be significantly reduced despite treatment. In these cases, the focus is on alleviating symptoms and making the remaining time as comfortable as possible. Early detection and treatment is therefore crucial to delay the progression of the disease.
Kidney transplantation as a treatment option
Kidney transplantation is a complex and costly option that may be considered for cats with severe chronic renal failure. This procedure requires careful selection of a suitable donor animal and intensive follow-up care to ensure the health of both the recipient and donor animals. Ethical considerations, including the quality of life of the donor animal, must be carefully weighed.
Despite the technical feasibility of a kidney transplant, many pet owners and veterinarians are skeptical about this option because it involves high risks and a long recovery period. Alternative treatments such as stem cell therapy may offer less invasive options in the future to improve kidney function and prolong the life of cats with kidney disease.
