Abstract
Increasing water intake and decreasing urine concentration are recommended for cats with urolithiasis and with idiopathic cystitis. Fountains are advocated to encourage drinking; however, effects on drinking of fountains have not been reported in cats living in pet owners homes. Thirteen healthy cats were assigned to have 24-h water intake and urine osmolality and specific gravity measured when water was offered from a bowl or fountain. One cat developed excessive barbering, vomiting, and refusal to drink water offered from the fountain. For the remaining 12 cats, intake was slightly greater from the fountain. However, urine osmolality was not significantly different. In this study, a fountain failed to substantially increase water intake and dilute urine in cats. A similar study including a greater period of time and additional cats may clarify the results of this study.
