A composition for pet food, including 5% by mass or more of fat, and a measured value (X) of the following deformation test is 0.5N or more at 25℃, and less than 0.1N at 60℃. Deformation test: a measurement object is placed on a flat plate, and a load is applied to a central portion of the measurement object from an upper side thereof using a plunger (having a cylindrical shape with a diameter of 15 mm and a thickness of 5 mm), and the stress is measured while advancing the plunger downwardly at a constant speed. The maximum value of the stress from when the plunger comes into contact with the measurement object until when the plunger advances 4 mm is measured. The measurement is repeatedly conducted with respect to 3 samples, and the average value of the maximum values is determined. The unit of the determined average value is converted to Newton (N), and defined as the measured value (X).一種寵物食品用組成物,其含有5質量%以上之油脂,就下述變形試驗中之測定值(X),於25℃下之值為0.5N以上,於60℃下之值為小於0.1N。變形試驗:在平皿上放置測定對象物,於其中央部自上方推壓柱塞(直徑15mm、厚度5mm之圓柱狀)而施以負荷,並一面將柱塞以一定速度朝下方行進一面測定應力。求取柱塞與測定對象物接觸而始以至前進4mm為止之期間的應力之最大值。針對3個樣本重複測定,求取該最大值之平均值。並將所獲得之平均值的單位變換成牛頓(N)而予設為測定值(X)。
