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. 

Hill's® Prescription Diet® k/d® Early Support is a food specifically designed to meet the needs of cats with early kidney disease. The nutrition of k/d® Early Support has been clinically shown to sustain kidney function and healthy body condition in cats with kidney disease.

For best results & safety practices:

  • Make sure fresh water is always available and feed more wet food if possible (hydration is important for cats with kidney disease).
  • Bring your pet in for regular checkups.
  • To prevent suffocation, keep the packaging out of the reach of pets and children.
