PURPOSE: A production method of liquid feed for pets is provided to enable the pets to secure stable defecation of the pets, and to maintain the proper body weight of the pets. CONSTITUTION: Edible meat, fishes, and byproducts thereof are mixed with pumpkin in a crusher, or are mixed and frozen together before drying and crushing (S10). The obtained material is crushed into a size smaller than 10 meshes (S20). The crushed material is inserted into more than two filtering sheets (S30). 100 parts by weight of materials inside the filtering sheets are mixed with 100-1,000 parts by weight of purified water, and the mixture is heated at a temperature higher than 100°；C and in the high pressure greater than 1.1 for 4-10 hours to obtain a first extract (S40). Oil and residues are removed from the first extract, and taurine is added to the extract to obtain a second extract (S50). The second extract is rapidly cooled and transferred to a packing machine to be inserted into a packaging container (S60). The sealed packaging container is sterilized and cooled before storing (S70).
