Survey of dietary and medication practices of owners of cats with chronic kidney disease.

The objective of this study was to describe the dietary and medication patterns of cats with chronic kidney disease (CKD). In this prospective, cross-sectional descriptive study, owners of cats with CKD were asked to complete a web-based survey. The study was advertised on CKD-, pet-, veterinary- and breed-associated websites and list serves. Owners of 1089 cats with CKD participated in the study. The mean reported age of the cats with CKD was 13.7 ± 4.2 years. Forty percent (430/1089) of cats had concurrent diseases, with hyperthyroidism, heart disease and inflammatory bowel disease being the most common. Veterinarian recommendation was the most common reason reported (684/1032; 66%) for diet selection, and 51% (556/1089) of owners fed a veterinary therapeutic diet formulated for kidney disease as some component of the diet. Many owners (466/1079; 43%) reported that their cats had an abnormal appetite; of these owners, 52% responded that their cats had a poor appetite or required coaxing to eat 5-7 days per week. Forty-seven percent and 51% of cats were receiving subcutaneous fluids and oral medications, respectively; however, most cats (811/1036; 78%) were not receiving phosphorus-binding medications. Fifty-six percent and 38% of cats received commercial cat treats and dietary supplements, respectively. Anorexia or hyporexia is a common problem in cats with CKD and may lead to cats being fed suboptimal diets for their disease. This information may be useful for treating or designing nutritional studies for cats with CKD.
