【Example】

Example 1 Bromthymol blue powder, which is a pH indicator, was previously dispersed and adhered to granular slaked lime for increasing the pH at a ratio of 0.1% by weight, and the urine absorbs water and solidifies 9% by weight. The weight ratio of bentonite sand is 64
%, And sepiolite sand for absorbing urine and absorbing deodorant in a weight ratio of 27% were dispersed and mixed. At that time, the sand is white or milky white in a dry state, and the pH indicator is so small that the color does not appear at all. When the urine of a pet animal hamster is dripped there, the wet part develops or changes its color from patina to blue. The pH at that time is 7.5 to 7.8. In addition, as a result of leaving this sand in a constant humidity chamber having a humidity of 80% for 24 hours, the sand itself has a hygroscopic property, so that it does not become wet and is not colored or discolored.

Example 2 Bromthymol blue, which is a pH indicator, was diluted with water to 1.00
Granular cristobalite is impregnated with 30% by weight of an aqueous solution diluted 0 times, and the supported product is 9% by weight, granular slaked lime for increasing pH is 9% by weight, and urine absorbs water and solidifies. Bentonite sand for weight ratio of 60
%, And 22% by weight of sepiolite sand for absorbing urine and deodorizing, and the like were dispersed and mixed. The cristobalite granules at that time are yellowish brown, and the overall color of the sand is white or milky white in the dry state. When the urine of a pet animal hamster is dripped there, the peripheral part of the wet part of the cristobalite granules develops or changes color from green blue to blue,
The colored and discolored part spreads out gradually. The pH at that time is 7.5 to 7.8. In addition, as a result of leaving this sand in a constant humidity chamber having a humidity of 80% for 24 hours, the sand itself has a hygroscopic property, so that it does not become wet and is not colored or discolored.

Example 3 Bromthymol blue, which is a pH indicator, was diluted with water to 1.00
An aqueous solution diluted 0-fold was mixed with the Kushibushi-gaze mixed clay powder in a weight ratio of 30%, and the mixture was kneaded and granulated in a weight ratio of 9%,
9% by weight of granular slaked lime for increasing H, 6% by weight of bentonite sand for absorbing and solidifying urine.
0% and 22% by weight of sepiolite sand for absorbing urine and deodorizing were dispersed and mixed. The clay granules at that time are yellowish brown, and the overall color of the sand is white to milky white in the dry state. When the urine of a pet animal hamster is dripped there, the clay granules in the wet part collapse and the peripheral part develops or changes color from greenish blue to blue. Furthermore, the colored and discolored portions spread out gradually. The pH at that time is 7.5 to 7.8. In addition, the humidity of this sand is 80
%, The sand itself has a hygroscopic property, so that the sand itself does not become wet and does not develop or discolor.

Example 4 When cresol red was used instead of bromthymol blue, which is the pH indicator in Examples 1, 2 and 3, etc., it turned yellow to red, and when alizarin red S was used. Turns red.

Example 5 A case where malic acid for lowering pH was dispersed and mixed in a weight ratio of 9% with respect to the sand material in place of granular slaked lime which was a mixture of Example 1, Example 2 and Example 3, etc. , The part of the pet animal hamster wet with urine turns yellow.

Example 6 When methyl red was used instead of bromthymol blue, which is the pH indicator of Example 5, it turned yellow, and when chlorphenol red was used, it turned purple.

Example 7 A mixture of bentonite (67% by weight) and sepiolite (33% by weight) having water-absorbing and solidifying sand was mixed with navy blue dye pigment powder (0.01% by weight). The mixture was dispersed and mixed in proportion. At that time, the sand shows a color or milky white in a dry state, and the color of the dye does not appear at all because the amount of dye pigment is very small. When the urine of a hamster, a pet animal, is dripped there, the navy blue dye color is colored in the sand in the wet part. Also,
As a result of leaving this sand in a humidity chamber with a humidity of 80% for 24 hours,
Since the sand itself has hygroscopicity, it does not get wet with water and does not develop or discolor.

Example 8 Instead of the dye / pigment powder of Example 7, commercially available microcapsules coated with and encapsulating a dye / pigment powder with a cellulose which is easily dissolved and disintegrated in an aqueous solution were used. In the wet part, the color of the pigment is colored in the sand as the microcapsule film dissolves and disintegrates.

[0019]

EFFECTS OF THE INVENTION By coloring or discoloring the wetted part of an animal, it is possible to easily distinguish that part from the other part. This makes it easy to quickly and accurately remove the sand from the urine portion. This suppresses the generation of offensive odors and germs in the living environment, and makes it possible for both humans and animals to live a comfortable life.
