Abnormal Kidney Imaging

Such as abdominal ultrasound, radiographs (X-rays)

Performing an Abnormal Kidney Imaging will help us clearly understand the condition of the kidneys. We can assess if the kidneys are in good shape, if both kidneys are healthy, and if there are any signs of kidney atrophy, among other things.

The interpretation of blood test values can be influenced by factors such as food and water intake. For example, if a cat doesn't eat, it may have lower CREA and BUN values. On the other hand, a cat on a raw meat high-protein diet may experience an increase in BUN and creatinine concentrations, even if its kidneys are functioning normally. 

Having an accurate understanding of your cat's kidney health is crucial to ensure proper care and avoid any potential mistreatment. It is not uncommon to see cats, when brought in for a check-up, with only one functioning kidney remaining.


When evaluating a cat's kidney health, your veterinarian will take into account various factors such as urine concentration, pH level, and the presence of protein, blood cells, bacteria, and other abnormal cells. These indicators collectively provide valuable information about the overall well-being of a feline's kidneys. 

For cats, a healthy urine specific gravity should be greater than 1.035.

In suspected cases of chronic kidney disease, it is essential to culture a urine sample to eliminate the potential presence of bacterial infection in the urinary tract. This step helps ensure an accurate diagnosis and appropriate treatment plan.

Blood Test

Blood tests are a valuable tool in measuring the levels of blood urea nitrogen (BUN) and creatinine, which are important waste products. However, when it comes to assessing kidney function, creatinine is generally considered a more specific indicator. If there is a rise in the concentration of these compounds in your cat's blood, it could be an indication that his kidneys are experiencing some difficulties with their function.
