Cats Kidney Problems

Cats Kidney Problems ! : kidneys are vital organs for both cats and humans. They keep the body’s own fluid balance in balance by removing toxins and waste substances from the blood. In addition, the kidneys produce various substances that are of great importance for red blood cells, blood pressure and calcium balance.

But what if the kidneys start to fail?

Kidney failure is common in older cats. A distinction is made between two different types of renal insufficiency. Here is a brief overview.

Acute Renal Failure (ANI)

Cats Kidney Problems

Acute kidney failure occurs suddenly. The ANI can be triggered, for example, by hypothermia, an ingestion of toxins, an accident with high blood loss or bacteria or infections. This type of kidney disease occurs less often in cats than chronic kidney failure (CRF) and, in contrast to CRF, has a higher chance of recovery. In some cases, however, acute renal failure can develop into chronic kidney failure.

Cats with ANI often have very high blood values. The ANI is a medical emergency that should be addressed by a veterinarian as soon as possible.

Cats Kidney Problems : Symptoms of ANI

Cats Kidney Problems

The following symptoms occur with ANI:

  • Vomit
  • Diarrhea
  • Strong pain
  • Not hungry
  • No urination or excessive urination
  • Bad breath
  • Conspicuous behaviour such as listlessness etc.

The kidney area is painful for the cat and warmer than the rest of your body.

If you have these symptoms, please go to the vet directly! Kidney failure can be life-threatening to your cat. Acute as well as chronic kidney failure must therefore be treated immediately by the veterinarian.

Chronic kidney failure (CRF)


Chronic kidney failure (CRF) is one of the most common diseases in cats over the age of 9. CKD occurs gradually in cats and can progress over months and years without the cat owner noticing anything. Only when most of the kidney tissue is destroyed do the signs of kidney disease appear.

The CRF is usually not curable. However, treatment and diet can stop the disease from progressing.

Failure to treat CRF is life-threatening for the cat and could dehydrate it.

Cats Kidney Problems : Symptoms of CRF

The following symptoms occur with CRF:

  • Vomiting regularly
  • Long-term weight loss
  • Not hungry
  • More thirst
  • Fur in poor condition
  • Pale mucous membranes
  • Frequent urination

If your cat has any of these symptoms, please see your vet!

Treatment & Diet

A cat from 7 years of age should be examined more often by the veterinarian in order to be able to recognize possible renal insufficiency quickly and consequently treat it.

If the veterinarian has diagnosed CRF in the cat, the veterinarian will take the next steps. Depending on the degree of illness, the vet decides on medication and further treatments.

In order for the CKD not to progress any further, the cat must be given special diet food. Often, kidney diet food is not immediately accepted by the cat because the food does not contain sugar, but the protein content is very low. It is therefore advisable to change your diet slowly, week after week. Unless otherwise prescribed by the vet, the diet food should initially be mixed with the usual food. The amount should be increased a little bit each day. If the cat does not eat the diet food, a small drop of tuna oil can be added during the changeover period. It also helps if the diet food is warmed up a little.

The changeover time can be between 2 to 6 weeks. After the conversion, however, the cat should only be fed the diet food. Additions or the usual treats are no longer allowed. Please keep to the agreement with your veterinarian.
