The purpose of this study is to evaluate the influence of kibble shape and fiber content of commercial dry foods on gastric emptying in healthy cats. Eight healthy cats were used to evaluate four different diets which varied in shape of kibble (round versus triangle) or fiber content (low versus high). Diets were labeled with 99m Tc‐mebrofenin and gastric emptying was evaluated with nuclear scintigraphy. There was a significant difference between the kibble shapes at both T 50 and T 20 . The triangle shaped kibble required significantly longer time than the round kibble to reach T 50 ( P = 0.02) and T 20 ( P =0.001). Diet fiber content did not have a significant influence on T 50 , and T 20 ‐ The influence of caloric and water intake was assessed with division of cats into high, medium, and low intake groups. The caloric intake had its main effect at T 50 with the lowest quartile of caloric intake requiring significantly less time to reach T 50 than the middle group and upper quartile ( P = 0.05). Water intake did not have a significant effect on gastric emptying in this study. There was no relationship or correlation between the surface area of the food (cm 2 /kg) and T 90 , T 50 , and T 20 .
