One out of 3 cats may develop kidney disease in their lifetime. This disease can be difficult to spot in cats, as signs may not be visible until 75% of kidney function is lost. However, the SDMA™ test can detect kidney disease months and even years earlier, when as little as 25% of kidney function is lost. Kidney disease is more common in advanced age, but with early detection & intervention, kidney disease can be stabilized. If your cat's age is advanced, ask your veterinarian about the SDMA™ test for early detection of kidney disease. Feeding the right nutrition early in the disease can help transform the lives of cats with kidney disease.
