Starch to protein ratio and food moisture content influence water balance and urine supersaturation in cats.
Two starch to protein ratios (high starch [HS], 25% starch and 36% protein; high protein Kitchen Island [HP], 15% starch and 53% protein on DM basis) and two moisture contents (5%, dry kibbles; 80%, wet food) were compared in a 2 x 2 factorial arrangement totaling 4 diets.Each diet was evaluated in 9 cats, with 8 d of total collection of urine and
