Abstract

Animal litter for animals which consist of a plurality of granular materials, wherein the granular materials contain aromatic granular materials each of which has base material which generates heat by absorbing water and an aromatic component adsorbed onto the base material. According to the present invention, the animal litter for animals, which are not emitting a strong scent regularly, but emit a strong scent by absorbing an animal's excrement, and thereby effectively restrain the stench emitted from the excrement, can be provided.

Claims (11)

1. A method of manufacturing animal litter for animals, comprising:

a granulation step of obtaining a base material by adding an alkali metal component to granules of a material which generates heat when absorbing water, followed by heating at a temperature of 100° C. or above,

an aromatic component adsorption step of obtaining an aromatic granular material after the heating step by adsorbing an aromatic component onto a first portion of the base material so that the amount of the aromatic component absorbed is 0.005% or more and 1% or less with respect to the amount of said first portion of the base material, and

a mixing step of mixing a second portion of the base material free of the aromatic component and the aromatic granular material.

2. A method of manufacturing animal litter for animals according to claim 1 , wherein the aromatic granular materials constitute 10% or more of the granular materials by mass.

3. A method of manufacturing animal litter for animals according to claim 1 , wherein the aromatic component is adsorbed near the surface of the base material.

4. A method of manufacturing animal litter for animals according to claim 1 , wherein the animal litter is configured to release 40 calories or more of heat when 20 cc of 1% by mass physiological saline solution is adsorbed.

5. A method of manufacturing animal litter for animals according to claim 1 , wherein the base material is porous.

6. A method of manufacturing animal litter for animals according to claim 1 , wherein the base material is at least one material selected from the group consisting of bentonite, acid clay, silica gel, and diatomaceous earth.

7. A method of manufacturing animal litter for animals according to claim 1 , wherein the base material comprises bentonite or acid clay that has been treated with an alkali metal.

8. A method of manufacturing animal litter for animals according to claim 1 , wherein the base material is granulated by a granulator adjusted so as not to include coarse grains of 10 mm or more.
