First Signs of Trouble

• An increase in thirst and excessive urination are the first signs of possible kidney failure. A visit to the veterinarian to determine the cause of the problem by examination, blood tests and urinalysis is necessary.
  
  

Further Signs

• About 30 percent of kidney capacity is needed for normal functioning of the kidneys. Often symptoms such as loss of appetite, nausea, vomiting, weight loss, poor hair coat, lethargy and weakness are not noticeable until 70 percent of kidney functioning is lost.
  
  

Causes

• Kidney failure is caused by age, genetics, environment or disease.
  
  

Prevention/Solution

• Cats that are 7 years old or older should have their blood tested, and urinalysis and blood pressure checked at their yearly check-ups. Cats that are kept indoors have less risk of drinking contaminated water, which could cause kidney failure.
  
  

Breeds At Risk

• Maine Coon, Abyssinian, Siamese, Russian Blue, Burmese and Balinese cats have a greater risk of kidney failure than other breeds.
  
  

Treatment

• Treatment for kidney failure in cats consists of replacing fluids lost and a diet low in protein, salt and phosphorus to reduce the amount of waste produced so the kidneys will not have to work as hard. In more severe cases, subcutaneous fluids and intravenous fluids might need to be given along with medications.
