Moisture absorbing efficiency of excrement is enhanced by providing a high degree of porosity and a high porosity ratio to a hydraulic granulated body and a non-hydraulic granulated body in a method of manufacturing a granulated body for absorbing excrement of animals. There is provided a method of manufacturing a granulated body for absorbing excrement of animals, characterized in that a dry bamboo fiber (1) and a wood fiber (2) are used as chief material, the said dry bamboo fiber (1) and wood fibers are mixed with each other while adding moisture thereto and the dry bamboo fiber (2) are allowed to absorb the moisture, the resultant is granulated to form a wet granulated body (3), hot air is blown to the wet granulated body (3), the moisture absorbed in the dry bamboo fiber (1) is transpired outward through the wet granulated body (3) by the hot air, and a porous structure in the dry bamboo fiber (1) in the wet granulated body (3) is reproduced by the transpiration and an infinite number of transpiring paths are formed in the wet granulated body (3) to obtain a porous structure. <IMAGE>
