Description of the Related Art Conventionally, as a method of treating excrement of animals, particularly pets represented by cats, a method of laying paper such as newspaper or toilet sand in a toilet has been adopted. In the case of paper, if it is soiled with excrement, it is discarded together with the excrement and replaced. However, if the exchange is not performed very frequently, a bad smell or a hygiene problem occurs. Also, paper is not a favorite material for animals with the habit of trying to bury and hide excrement. In the case of toilet sand, there are mainly two types: one in which excrement is washed with water, dried and then reused, and another in which only the part of the excrement that has absorbed the moisture is hardened so that only that part is discarded. Zeolite is mainly used for reuse, but excrement is present as it is due to poor absorption, causing odor. Furthermore, there is a problem that cleaning and drying for reuse are troublesome. On the other hand, the hardening type is a type of toilet sand which cannot be reused but is excellent in simplicity of disposal treatment, and is also preferred by animals having a habit of hiding excrement. However, there is still room for improvement in the hardness of the lumps after water absorption.
Further, there is a problem in that since all the absorbed water is discarded, the amount of used sand is large and a large amount of waste is generated.

である。Means for Solving the Problems The present inventors have conducted intensive studies in view of the above-mentioned problems. As a result, when a specific porous body that absorbs water and easily collapses in a pore structure is used as an excrement disposal material, it is difficult to absorb water before absorbing water. Because of the high bulk, the required weight of the processing material is small,
In addition, they found that the pores were crushed during water absorption, the volume was reduced, and the bulk of the waste could be reduced, and the present invention was made based on this finding. That is, the present invention comprises (1) an excrement treatment comprising a porous body obtained by freeze-drying an aqueous solution of at least one polysaccharide or its derivative, or a mixture of this aqueous solution and clay sol. Wood, (2)
The polysaccharide or its derivative is at least one or more selected from agar, starch, sodium alginate, methylcellulose and carboxymethylcellulose, and (3) the clay is bentonite (1). The above-mentioned excrement disposal material is provided.

It is manufactured from the resulting porous body. As the polysaccharide or a derivative thereof, a natural polysaccharide or a derivative thereof can be used, and specific examples include agar, starch, sodium alginate, methylcellulose, carboxymethylcellulose, agarose, dextrin, and mannan.

It is 0 to 70:30. By this mixing, the specific gravity of the porous body and the hardness of the lump when the porous body absorbs water can be increased. If the amount of the clay sol is too large (the amount of the aqueous solution of the polysaccharide or a derivative thereof is too small), the lump is weak in hardness and may become sticky. At this time, as long as the properties of the porous body are not impaired, components other than the polysaccharide or its derivative and clay can be added, such as a fragrance, a pigment, an antibacterial agent, a deodorant, a fiber, and a specific gravity adjusting material. Can be used.

Freezing can be carried out by ordinary means such as liquid nitrogen or a refrigerator. Drying can also be carried out by ordinary means, and is usually freeze-dried under reduced pressure, but may be dried under reduced pressure without blowing. It is preferable to rapidly freeze the aqueous solution or the sol because a porous body having a uniform pore size and shape and high compressive strength can be obtained. Particularly preferably, the freezing is performed at a freezing speed of 1 × 10 −2 ml / sec or more (the volume of the sol or aqueous solution frozen per second is 1 × 10 −2 ml or more). The freeze-dried body thus obtained is a porous body having fine pores. Although the size of the pores of this porous body is not particularly limited,
In the case of an aqueous solution of a polysaccharide or a derivative thereof, the pore size is 0.5.

水する作用を有する。The excrement disposal material of the present invention can be made bulky by using a porous body made of a material that absorbs moisture and swells, but can be a small excretion disposal material. In addition, the excrement disposal material of the present invention has the advantage that the volume can be reduced because water absorption makes the pores easily crushed, and the volume at the time of disposal is reduced. The function of the polysaccharide or its derivative in the present invention is that it has an appropriate strength when dried, and absorbs water at a high speed to reduce the volume, and when clay and other particles are blended, It acts to firmly bond the particles and further increase the specific surface area. In addition, clay acts as an aggregate forming a porous structure, and has a function of absorbing water at a high speed, which is a characteristic of clay.

In this case, according to the present invention, the range (width) of the excrement disposal material in which the saline solution is diffused can be reduced. In the examples, the thickness (depth) permeated with the saline solution is larger than that of the comparative example, but by applying a load to the surface at the time of disposal, the holes are crushed to reduce the thickness to about half to about 2/3.
