Cats are beloved companions known for their independence and grace, but beneath their enigmatic nature lies a common health concern that affects a staggering number of feline friends worldwide. Kidney disease, also known as renal disease, is the number one disease our kitties succumb to. I hold it close to my heart, as I have lost many patients and one of my cats to this disease. As responsible pet owners, it is crucial to be aware of the signs, prioritize preventive measures, and understand the importance of regular bloodwork for early detection. Studies suggest that approximately 30% of cats over the age of ten may develop kidney disease. These numbers are alarming, emphasizing the need for increased awareness and proactive care.

Recognizing the Signs:

One of the challenges with kidney disease in cats is its subtle progression. Early symptoms can be easily overlooked or attributed to the normal aging process. Pet owners should remain vigilant and watch out for potential signs, including increased thirst and urination, weight loss, decreased appetite, lethargy, vomiting, and changes in litter box habits. If any of these symptoms persist or worsen, it is essential to consult a veterinarian promptly.

The Role of Bloodwork and Early Detection:

Getting cats started on therapy, which can be as simple as a food change, early in the disease process can add years to their life. Regular bloodwork is a vital tool for the early detection and monitoring of kidney disease in cats. Blood tests, such as serum chemistry panels and urinalysis, provide valuable insights into kidney function. These tests can detect elevated levels of waste products in the blood and abnormalities in urine composition, indicating potential kidney problems. Timely bloodwork allows veterinarians to identify kidney disease in its early stages, enabling them to develop an appropriate treatment plan and improve the chances of a favorable outcome.


Kidney disease is a silent epidemic that affects a significant number of cats worldwide. By remaining vigilant and proactive, cat owners can play a crucial role in the early detection and management of this condition. Regular bloodwork is an essential tool in identifying kidney disease in its early stages, enabling veterinarians to intervene promptly and improve the cat’s overall prognosis. Remember, your cat’s well-being depends on your attentiveness and commitment to their health. Together, we can ensure a longer, healthier life for our feline companions.
