Abstract

Ten percent of all cats spray in adulthood. The sequence of urine spraying and its triggering stimuli are analyzed and its pharmacological treatment summarized. Clomipramine (Anafranil®) has been tested on 26 cats at the dosage of 5 mg once a day. Results are highly significant: clomipramine is responsible for a reduction of urine spraying (of more than 75%) in 80% of the cats. In clinical use, clomipramine is recommended at the dosage of 0.25 to 0.5 mg kg−1 twice a day.
