Kidney Failure in Cats
This occurs in older cats. So what contributes to kidneys failing?The kidney regulates blood pressure, so it is common for cats with kidney failure to also suffer from hypertension which is known as high blood pressure in the arteries, persistently elevated. In the long term this can cause coronary artery disease, stroke, heart failure, and atrial fibrillation.
Reasons the kidneys could start to fail include poisoning, ingestion of a toxic substance such as anti-freeze or poisonous plants, heatstroke, trauma, blockage, arterial thromboembolism, pancreas failure, and infection.
If acute kidney failure is not recognised and treated, cats will suffer permanent kidney damage and even death; chronic kidney failure causes many secondary problems over time, including a decrease in calcium levels that can lead to bone demoralisation.
What are the symptoms? These include decrease in appetite, weight loss, vomiting or diarrhea, lethargy or depression, dehydration, ulcers in the mouth or bad breath. A cat may be experiencing kidney problems if it has pain in the kidney area or unusual urination or constipation.
If your cat is in final stages this means 90 percent or more damage: symptoms include seizures, loss of consciousness, tremors, uncontrollable vomiting and going into a coma.
The kidneys help regulate blood pressure. With aggressive therapy acute renal failure can be corrected in some cases.
In severe cases, treatment will be hospitalisation, administration of intravenous fluids, diuretic therapy or medications, close monitoring of important electrolytes such as potassium, sodium and calcium medications to control blood pressure.
