Since the 1950s, dietary therapy has been the cornerstone for the treatment of chronic kidney diseases (CKD) in dogs and cats. It continues to be the most common recommendation made for affected feline patients and is credited with the highest strength and quality of evidence.1 In addition to protein restriction, dietary modifications include reduced phosphorus and sodium, increased omega-3 polyunsaturated fatty acids, adaptations to promote neutral acid-base balance, and possibly increased caloric density, B-vitamins, and fiber. Combined, they provide a beneficial “renal effect,” however, evaluation of the effect of individual components remains untested. Assessing these components individually remains an important goal in order to optimize outcome and reduce detrimental effects.
