Common symptoms of kidney problems

Frequent urination & excessive thirst

Kidney failure in cats leads to increased urination and thirst. The damaged kidneys prevent waste products and excess water from being excreted sufficiently. The body tries to compensate for the loss of liquid by having the cat drink more and visit the litter box more often.

Reduced appetite & weight loss

In the case of renal insufficiency, the cat's appetite is often reduced. The damaged kidneys cannot process important nutrients properly, which affects appetite. As a result, the cat consumes less food and weight loss occurs as the body uses muscle mass for energy.

Dehydration & vomiting

The damaged kidneys cannot retain enough water in the body, leading to dehydration. The cat will show signs such as dry gums and sunken eyes. Kidney problems can also cause nausea and vomiting because waste products remain in the body and irritate the lining of the stomach.

Fatigue & Lethargy

Kidney failure leads to disturbances in the cat's electrolyte balance and metabolism. This creates an imbalance that leads to fatigue and lethargy. The body is weakened and the cat shows less activity, sleeps more and has less interest in play and exercise.

Helping with kidney failure: symptoms, stages and treatment for cats

Chronic or acute renal failure are diseases that primarily affect older cats. If left untreated, kidney failure can lead to kidney failure, but there are now a number of treatment options that can slow down the progression of the disease and improve your four-legged friend's quality of life.

Stages of renal insufficiency in cats

In order to be able to correctly classify the symptoms of kidney failure, you should also know about the different stages of this disease:

Stage 1: In this stage, your cat is suffering from mild kidney failure . Apart from a slight increase in blood creatine levels , no obvious symptoms can be identified . The disease usually goes undetected at this stage, but once diagnosed, it can be managed with dietary changes and regular monitoring of symptoms.

Stage 2: In this stage, your cat has mild to moderate kidney disease and the first symptoms are noticeable. The cat drinks and urinates more than usual, has less appetite and loses weight .

Stage 3: In this stage of kidney disease, the symptoms become even more noticeable than before. The cat can become dehydrated, vomit and behave listlessly . Blood tests can show a significantly elevated creatine level. Chronic At this stage, renal failure can become chronic if not diagnosed in time.

Stage 4: In this final stage, the kidney failure is already chronic. The kidneys only work slightly. Your cat's blood can no longer be filtered, toxins can no longer be excreted and poison the cat. Symptoms such as seizures or loss of consciousness may occur .

Look out for these symptoms in your cat:

  • frequent urination

  • excessive thirst

  • low appetite and weight loss

  • musty smell

  • dehydration and vomiting

  • fatigue and lethargy

  • seizures, loss of consciousness

Danger! These symptoms alone are not sufficient to infer current renal insufficiency, they can also be an indicator of diseases with similar signs, eg diabetes. It is important that you go to the vet immediately if you have any health problems.

Course of treatment in renal failure

As with most diseases, the same applies here - an early diagnosis can prevent a painful course of the disease. Kidney function can be counteracted with a special diet and medication, thus slowing down the progression of the disease. Intravenous fluid therapy may be necessary to balance fluid and electrolyte levels. With timely diagnosis and proper care, cats with renal failure can lead longer, quality lives.
