2016 ACVIM Forum Research Abstract Program

The mean number of urinations per day detected by VRS (2.5 AE 0.2) was significantly greater compared to caregiver observations (0.6 AE 0.2; P < 0.0001). Five of 19 cats were never observed by their caregivers in the litter box. The mean number of urinations per day detected by VRS was significantly higher for abnormal cats (2.9 AE 0.3) compared to healthy cats (2.1 AE 0.2; P = 0.02); there were no apparent differences in frequency between healthy and abnormal cats reported by caregivers (0.7 AE 0.3 and 0.5 AE 0.3 respectively). There were no differences in mean urination time between normal and abnormal cats determined by VRS or caregivers. Mean cover-up time determined by VRS was significantly longer in normal cats (23 AE 4 seconds/urination compared to abnormal cats (9 AE 5 seconds/urination; P = 0.03); differences in cover-up time were not detected by caregiver observations.
