Feline chronic kidney disease (CKD) is extremely common in middle-aged and older cats. Dietary management is one of the primary tools for slowing disease progression and maintaining quality of life, with important welfare implications.
CKD dietary management in cats presents a genuine welfare dilemma. The prescription kidney diet is medically optimal - reducing phosphorus intake slows disease progression, potentially extending the comfortable life of the cat by months to years. However, the diet's palatability is often poor, and forcing a cat to eat something they find unacceptable creates significant daily distress. A cat that stops eating entirely develops hepatic lipidosis rapidly - a life-threatening condition. The welfare balance point is not always clear: is it better to extend life on a diet the cat dislikes, or accept shorter survival on a diet the cat enjoys? Veterinarians and owners must make individualized assessments based on the severity of CKD and the individual cat's response to different management strategies.
