Kidney disease in cats is quite common and takes two main forms. Acute inflammation of the kidney tissues (nephritis) can arise as an extension of an infection elsewhere in the body; chronic nephritis is insidious in its onset and affects cats in their old age.
Chronic nephritis is a disease a veterinarian frequently encounters. As aged cats seem less prone to develop cardiovascular disease than dogs, the organ that seems to fail first in old animals is the kidney.
What are the final stages of kidney disease in cats?
- The affected cat tends to drink more water but this may go undetected for a long time until the cat is observed going into the bathroom and licking the wet tiles or jumping up and drinking from the kitchen sink.
- Gradually the cat loses weight, although he may continue to be bright and eat well.
- The increase in thirst and loss of weight continues until the cat becomes extremely thin and spends most of his days close to the water dish.
- He starts to lose interest in food and may approach the food apparently hungry, only to quickly lose interest and return to the water bowl.
- His gums may be quite yellow and there is an unpleasant smell from the mouth.
- In the final stages, the cat refuses all food, may start to vomit, and is reluctant to move.
Kidney disease in cats when to euthanize
If you have a cat with severe kidney disease, you may be wondering if it is time to euthanize your cat. The answer is that it depends on the quality of life your cat has and how well they are responding to treatment.
A cat with severe kidney disease or renal failure will develop an inability to control his own body functions such as urination, defecation, eating, and drinking. These are all symptoms that indicate that death is near, and you may want to consider euthanizing them.
The decision to euthanize a pet can be one of the hardest decisions you ever have to make. But sometimes all other alternatives have been tried and failed, and there’s no longer any hope for your pet.
Is kidney disease in cats treatable?
Unfortunately, chronic nephritis is not curable. Vital tissues in the kidney have been destroyed and will not regenerate. There are some measures that can be taken that should slow the progress of the disease and prolong the active and comfortable life of the pet.
How do you treat a cat with kidney disease?
Changes in the diet are aimed at reducing the overall protein level and substituting other sources of nutriment. Cats are probably prone to kidney disease because their preferred diet is extremely high in protein, the waste products of which must be excreted by the cells of the kidney. Such foods as liver and kidneys should be avoided.
Cats usually will not eat large quantities of carbohydrates but will accept quite high levels of fat. The addition of vegetable or animal oils or lean meat or chicken may allow the overall amount of meat to be reduced. Cheese, yogurts, and milk also are useful low-protein additions to the diet.
Extra vitamins in the form of the Vitamin B group are usually prescribed and anabolic steroids help reduce the amount of protein broken down and therefore excreted by the kidney.
The cat must be allowed free access to water, as it is by increasing the urinary flow through the kidneys that the waste products are removed and are prevented from building up in the bloodstream and producing the toxic effects already described.
The cause of chronic nephritis in the cat is not known. It is suspected that bacterial infections from fighting may play a part in the destruction of kidney cells early in the cat’s life.
In the acute disease, the cat becomes suddenly very depressed, may vomit, refuse food and be very tender when handled around the abdomen. The urine may be very dark and often contains blood. Usually, the cat has been in a fight and may have a badly infected wound or abscess. Acute nephritis can result from infections of the teeth.
The treatment of acute kidney disease consists of keeping the cat in the hospital and giving it fluids by injection and administering antibiotics until the kidney tissues show signs of recovery.
Conclusion of kidney disease in cats
It’s important to remember that there is no cure or reversal for kidney disease. The best you can do is manage their condition through diet, medication, and other supportive care.
Cats with kidney disease are often dehydrated, so consider giving them canned food as much as possible and trying to entice them with water fountains or flavored water.
They also need medications throughout their life, so make sure you consult with your veterinarian regarding what medications they should be taking.
You should speak with a veterinarian or other expert to get advice on what to expect from a cat with kidney disease.
