Heir interaction. If there was a important F-test, imply separation was completed by the PROC MIXED PDIFF statement. Inside a subset of cats that had a serum SDMA 14 g/dL at baseline or for the duration of the 6-month feeding trial, a single measure t-test was performed to evaluate the effect of time on food. Information are reported as least square signifies (LSM) SEM. Statistical significance was declared at P 0.05.ResultsA total of 80 cats completed the six month study. Eighteen of 51 cats (35.three ) consuming test food, and 7 of 54 cats (13.0 ) consuming owner’s-choice foods had incomplete information or failed to complete the study. On the 80 cats completing the study, imply age was 11.5 years (variety, 9 to 18 years). There have been 31 males and 49 females, with imply SD initial physique weight of 5.four 1.five kg (variety two.8.five kg) (Table two). Concentrations of blood hemoglobin, and serum sodium and renal function biomarkers in cats at baseline, 3 months, and 6 months are shown in Table three (least square suggests SEM). Cats consuming test food showed considerable decreases in serum Cr and BUN concentrations across time. Cats consuming owner’s-choice foods showed substantial increases in serum SDMA concentrations at three and 6 months compared with baseline (all P 0.05). For serumTable two.

For serum sodium (P = 0.02), there was a significant interaction in between diet plan and time on study. Urine specific gravity in cats consuming owner’s-choice foods also showed important decreases at three and six months compared with baseline (all P 0.05). There was no change in either group of cats for urine protein:Cr ratio across time.Table 3.
