2018 ACVIM Forum Research Abstract Program: Seattle, Washington, June 14 - 15, 2018

A group of 12 healthy adult cats were fed two commercially available foods a,b (1g sodium/1000 kcal and 3.5g sodium /1000 kcal), in series, for 2 weeks each and 24 hour urine samples were collected at the end of each period and evaluated. The COT test was performed and Equil 2 software was used to calculate RSS from urine concentrations of NH + 4 , Ca +2 , Cl -, Citrate, Mg +2 , oxalate, PO −3 4 , K + , Na + , SO −2 4 and urine pH. SAS™ version 9.2 was used for all analyses. A repeated measures regression model was used with the value of the analyte as the dependent variable and food as the independent variable. Least-square means and pair-wise differences were calculated for diet comparisons for each analyte. Two-sided tests were performed. An alpha of 0.05 was used to determine statistical significance.
