Research Communications of the 27(th) ECVIM-CA Congress: Intercontinental, Saint Julian's, Malta, 14th to 16th September 2017

Thirty-three cases were recruited and supplied with Diet A (n = 17) or Diet B (N = 16) according to the randomization procedure. The mean time of struvite dissolution was 13.1 days and 14 days respectively for diet A and Diet B (n.s). The mean time to disappearance of at least one urinary sign was 7 days for diet A and 11.4 days for diet B (P = 0.03). On D7, all cats from group A and 75% of cat from group B had no more urinary signs (P = 0.04). Mean urinary pH was decreased in groups A and B at the end of the study (6.1 AE 0.5 and 6 AE 0.6, respectively) compared to D0 (7.2 AE 0.8 and 7.2 AE 0.7, respectively). In group B, urine specific gravity significantly decreased (P = 0.01) from D0 (1.046 AE 9.8) to the end of the study (1.036 AE 12.5). In group A, urine specific gravity decrease was not significant. Two and 4 cats of groups A and B respectively exhibited transitory adverse events, possibly related to the diet (mild diarrhea or mild vomiting). These events resolved spontaneously and did not lead to the exclusion of any cat.
