Chronic Kidney Disease in Cats
What is chronic kidney disease and what causes it?
The kidneys are two organs that enable your cat to get rid of waste products and excess fluid from the
body. They do this by producing urine. When the kidneys are not working
properly waste products start to build up in the body which in turn cause
your cat to feel unwell. Chronic kidney disease is a common condition of
older cats. Usually by the time to condition is diagnosed around 75-85% of
the kidney function has already been lost. We cannot repair this damage
but we can give your cat medication to help him/her feel better. The
underlying cause can often be difficult to find but can be linked to
inflammation or infection within the kidney.
How can chronic kidney disease be diagnosed?
We usually suspect your cat may be suffering from kidney disease by the symptoms she or he is
exhibiting. These may range from increased drinking and urinating, weight loss, vomiting and diarrhoea or
a reduced appetite. However, we can only confirm a diagnosis by carrying out the following tests:
1. A blood test to check for raised kidney values
2. A urine test to assess your cat’s hydration, for signs of infection and for protein in the urine
3. More in-depth investigations such as an ultrasound, xray or kidney biopsy may also be needed
How can chronic kidney disease be treated?
In the majority of cases it is not possible to cure chronic kidney disease but we can give supportive care to
make your cat feel better and live longer. The main treatment is changing your cat’s diet to one which is
formulated to help the kidneys function better. This has been proven to help your cat live for longer. The
diets come in a range of flavours and are usually accepted well if gradually introduced over several weeks.
We may also prescribe your cat medication to help with the some of the secondary effects of kidney
disease such as high blood pressure, increased protein levels in the urine (which is an abnormal finding
that is common in cats with kidney disease), anaemia and dehydration.
How will I know if my cat is feeling better?
You will usually notice that your cat has an improved
appetite and has more energy at home. We will usually
advise you come in for regular assessments of your cat’s
blood values, urine and blood pressure after an initial
diagnosis of kidney disease. This enables us to ensure we are
giving the correct treatment and at the correct doses.
How will the disease progress?
Chronic kidney disease is usually diagnosed when around 75-85% of the function has been lost and cannot
be repaired. Supportive treatment can help your cat feel better but will not restore the normal function of
the kidneys. Survival rates once a diagnosis has been reached can range from weeks to years. For this
reason it is very important for your cat to be regularly assessed by us to ensure he or she is receiving all of
the necessary treatment.
