Description

  The present invention relates to an animal toilet used for animals such as cats kept indoors, and more particularly to an animal toilet that can easily clean the toilet and reduce the amount of cat sand discarded as garbage. .

  Cellulose formed into a granular shape by solidifying bentonite, pulverized pulp, etc. that hardens when it absorbs mineral zeolite, river sand, or urine in a plastic container as a toilet for animals such as cats and dogs kept indoors Toilet in which granular materials such as so-called cat sand are put is generally used. An animal such as a cat enters the toilet and excretes urine, feces and the like from the cat sand. The owner removes the cat sand, which is soiled with urine and stool, together with the stool with a scoop and removes it from the container, and replaces it with fresh cat sand.

  However, since cats stir the cat sand with their feet after excretion, the amount of cat sand contaminated with urine and stool increases, and the dirty cat sand is diffused, and it is not possible to completely remove only the dirty part. Can not. Moreover, the zeolite used as cat sand, river sand, etc. do not absorb urine, and bentonite and cellulose particles absorb urine to some extent, but cannot absorb completely. For this reason, urine tends to collect on the bottom of the container through the cat sand. For this reason, the owner discards all the cat sand in the container once a week or every two weeks, cleans the container and dry it, and then puts fresh cat sand into the container and cleans the toilet. It is necessary to keep on.

  In addition, since the cat sand is discarded every time the animal is excreted or replaced once every week or two, the amount of cat sand that becomes garbage is very large. Since mineral sand such as zeolite used as cat sand is nonflammable, there is a problem that it is difficult to treat it as garbage.

  As a solution to this problem, for example, an animal toilet as disclosed in Patent Document 1 has been developed. In this animal toilet, a water-repellent granular material is placed in a container whose bottom is a liquid-permeable structure, and a liquid-absorbing sheet supported by a support is placed under the bottom sheet of the container. Provided in close contact with the sheet, the urine passes through the water-repellent granular material, passes through the bottom of the container, and is absorbed by the liquid absorbent sheet. Since no urine remains in the container, the toilet only needs to be replaced once a day, and all the particulate matter needs to be replaced once a month or two. It is characterized by being able to reduce the amount of.

JP-A-10-229768

  However, in such a conventional example, a liquid absorbing sheet supported by a support is provided in close contact with the bottom sheet under the bottom sheet of the container. When the absorption amount of urine or the like increases in the liquid sheet, it returns to the granular material, and the entire granular material is soiled. Further, since it is assumed that the liquid absorbent sheet is replaced once a day, the replacement work is complicated and the amount of dust increases.

  This invention is made | formed in view of the above subjects, The objective is to provide the toilet for animals which can perform a toilet cleaning easily.

  FIG. 1 is an overall perspective view showing a first embodiment of the animal toilet according to the present invention, FIG. 2 is an exploded perspective view of the animal toilet of the first embodiment, and FIG. 3 is the first embodiment. FIG. 4 is a perspective view of a granular material storage container for storing granular material, which is an embodiment of the container according to the present invention, and FIG. 5 is a bottom surface portion of the granular material storage container. (A) is the perspective view seen from the upper surface side, (b) is the perspective view seen from the back surface side. 6 is a cross-sectional view showing the XX ′ cross section and the YY ′ cross section of the bottom portion shown in FIG. 5, and FIG. 7 is an X of a modification of the bottom portion of the granular material storage container shown in FIG. FIG. 8 is an explanatory diagram showing a liquid transition state in the arch portion, FIG. 9 is a diagram showing a state of dripping from the liquid guiding portion in a raindrop shape, and FIG. It is sectional drawing of the thickness direction which shows the structure of a liquid absorbing sheet. In these drawings, the dimensions are appropriately adjusted for easy understanding.

  As shown in FIGS. 1 to 3, the animal toilet 1 according to the present invention is a box-shaped granular material storage container 2 for storing granular materials, and is located below the storage container 2 and is incorporated in a freely removable manner. The liquid absorbent sheet container 3 for accommodating the liquid absorbent sheet 6 (FIG. 2) and the cover 4 installed so as to cover the side surface above the granular material container 2 are configured as main elements. And on the upper surface of the bottom face part 23 of the granular material storage container 2, a predetermined amount of the granular material 5 is spread and provided in layers. Further, a liquid absorbent sheet 6 (FIG. 2) is laid in the liquid absorbent sheet storage container 3.

  As shown in FIG. 4, the granular material storage container 2 has an opening 21 through which an animal enters and exits, and includes four side walls 22, a bottom surface portion 23 formed at a predetermined position of the side walls 22, and a lower frame 24. It is formed by molding a metal plate such as a polyethylene resin (PE), polypropylene (PP), polyolefin resin such as polyethylene-terephthalate (PET), or other plastic materials, and stainless steel. Also, an opening 25 is formed below one bottom surface portion 23 in one side wall 22a (the left side wall in the figure) of the four side walls 22.

  The liquid-permeable bottom surface portion 23 is configured so that, for example, liquid such as urine excreted on the granular material faces from the upper surface (surface in contact with the granular material) of the bottom surface portion 23 of the granular material storage container 2 to the back surface side (facing the liquid absorbing sheet). And a plurality of openings 26 are formed in a net shape, a slat-like shape, or the like. In the first embodiment, as shown in FIGS. 5 and 6, the bottom surface portion 23 is formed in a slat-like shape having a plurality of openings 26 and is integrated with the granular material storage container 2, and is made of plastic. Molded with materials. On the side facing the liquid absorbent sheet 6 (FIG. 2) of the widthwise crosspiece 27 that forms the slat-like shape, a liquid guiding portion 28 is formed.

  The liquid guiding portion 28 is for efficiently dropping the liquid such as urine that has passed through the opening portion 26 of the bottom surface portion 23 downward from the bottom surface portion 23, and is directed upward (on the side opposite to the liquid absorbing sheet). A plurality of arc-shaped arch portions 29 are continuously formed. The liquid is guided along the arcuate arch portion 29 and collected at the leading end portion where the end portions of the arch portion 29 are connected to each other, and efficiently drops from the bottom surface portion 23.

  As shown in FIG. 6, the arch shape of the liquid guiding portion 28 is an arc having a circular arc height h of about 4 mm and a chord length l of about 8 mm. The arch shape is preferably an arc having a height h of 3 to 5 mm and a length l of 6 to 12 mm, but is not limited to this. For example, FIG. As shown in b), it may be a shape such as a U-shape or an inverted V-shape that allows the liquid to be easily guided. In addition, the continuous arch-shaped liquid guiding portion 28 is formed on the crosspiece 27 in the short direction of the bottom surface portion 23 in the present embodiment, but may be formed on the crosspiece 27 'in the longitudinal direction. Moreover, you may form in any crosspiece 27 and 27 'of a longitudinal direction and a transversal direction. It is preferable to form the bi-directional rails 27 and 27 'in this way because the liquid is guided more efficiently. Further, in this case, by making the portion where the crosspieces 27 and 27 'intersect in both directions have a convex shape, the liquid gathers from both of the crosspieces 27 and 27' and easily falls down. It is more preferable.

  As a result, as shown in FIG. 8 (A), the liquid such as urine excreted by the animal passes between the granular materials 5 (FIG. 2) as indicated by arrows and moves to the arch portion 29 on the back surface side of the bottom surface portion 23. To do. The liquid that has migrated to the arch portion 29 efficiently gathers at the convex portion 30 (FIG. 6) formed by the arch portions 29 continuing along the arcuate arch, and becomes a large liquid droplet W below. It is dripped on the installed liquid absorbing sheet 6 (FIG. 2). For this reason, the excreted liquid such as urine is quickly discharged from the bottom surface portion 23. On the other hand, as shown in FIG. 8B, the conventional one does not have an arch portion as in the present invention formed on the back surface of the bottom surface portion, so that the liquid transferred to the back surface side efficiently drops downward. There is a fear that liquid such as excreted urine may remain on the bottom surface. In addition, since the liquid guiding portion 28 includes a plurality of continuous arch portions 29, the liquid is widely dispersed by the liquid guiding portion 28 when moving to the back side of the bottom surface portion 23, as shown in FIG. As described above, the liquid falls by being dispersed over a wide area of the liquid absorbent sheet 6. As a result, the liquid absorption efficiency of the liquid absorbent sheet 6 is improved. Further, when the liquid is absorbed unevenly, only a portion of the liquid absorbent sheet 6 is saturated, and it is prevented that the replacement timing of the liquid absorbent sheet 6 is advanced.

The size of the opening portion 26 formed in the bottom surface portion 23 (that is, the interval between adjacent bars 27 or 27 ′) is the minimum dimension of the granular material 5 (FIG. 2) provided on the top surface of the bottom surface portion 23. It is a shorter dimension and prevents the granular material 5 from falling downward from the opening 26. For example, when the granular material 5 having a diameter of 4 to 8 mm is used, the short side length is set to about 3 mm. When the granular material 5 has a cylindrical shape with a diameter of 5 mm and a length of 7 mm, the short side length is set to about 4 mm. Specifically, the opening 26 preferably has a short side length of 2 to 6 mm and a long side length of 3 to 5 mm. In addition, what is necessary is just to select this suitably according to the magnitude | size of the granular material 5 to be used. The area of each of the plurality of openings 26 is preferably 6 to 30 mm ² . Moreover, the opening ratio (hereinafter referred to as the opening ratio) that totals the opening area of the opening 26 allows liquid such as urine excreted by the animal to pass smoothly through the opening to the back side of the bottom surface. From the viewpoint of maintaining the strength that does not break even if an animal such as a cat is placed, it is 25 to 50%, preferably 40 to 45% of the area of the bottom surface portion 23. If it is less than 25%, it takes time for liquid such as urine excreted by an animal such as a cat to pass through the bottom surface portion 23, so that the liquid spreads to the granular material 5 side of the bottom surface portion 23 and stains the entire granular material. There is a fear. On the other hand, if it is larger than 50%, the strength of the bottom surface portion 23 becomes low, and there is a fear that the bottom surface portion 23 may be damaged when an animal such as a cat rides.

  The bottom surface portion 23 preferably has surface wettability. When having wettability, when a liquid such as urine comes into contact with the bottom surface portion 23, it spreads moderately, and the convex portion 30 (formed by the arch portions 29 continuing along the arch portion 29 of the liquid guiding portion 28. It is easy to gather at a portion where the crosspiece 27 in the short direction and the crosspiece 27 'in the longitudinal direction intersect. As a result, the liquid efficiently drops downward from the bottom surface portion 23. In order to impart this surface wettability, a surface active agent such as an antistatic agent or a nonionic surfactant is applied to the surface of the crosspieces 27 and 27 ′ forming the opening 26 of the bottom surface portion 23, or is formed. This is possible by kneading into the raw material of the plastic.

  In addition, although this bottom part 23 shall be integrated with the granular material storage container 2 in a present Example, it is good also as another body. That is, the bottom surface portion 23 may be configured to be detachable from the granular material storage container 2. In that case, although not shown, a holding bar for holding the bottom surface part 23 is provided at a predetermined position inside the side wall 22 of the granular material storage container 2 over the four circumferences, and the bottom surface part 23 is provided on this holding bar. May be installed. As a result, the bottom surface portion 23 can be removed, and only this can be cleaned. That is, it is possible to save time and labor when cleaning the animal toilet.

  As shown in FIGS. 2 and 3, the liquid-absorbing sheet container 3 is a drawer-like box composed of a bottom plate portion 33, three side plate portions 32 standing on the periphery of the bottom plate portion 33, and a front plate portion 31. As in the case of the particulate container 2, the body is formed by molding a plastic plate such as polyethylene resin (PE), polypropylene (PP), polyethylene-terephthalate (PET), or other plastic material, or a metal plate such as stainless steel. And it is installed in the lower part of the granular material storage container 2, It becomes the drawer | drawing-out body which can be freely inserted or extracted from the opening 25 (FIG. 4) formed in the granular material storage container 2. As shown in FIG. (The two-dot broken line in the figure shows a state in which the liquid absorbent sheet storage container 3 is pulled out.) That is, the liquid absorbent sheet storage container 3 is incorporated under the bottom surface portion 23 of the granular material storage container 2 so as to be freely inserted and removed. is set up. In other words, the animal toilet according to the first embodiment has a drawer structure that can store a drawer body, and the liquid absorbent sheet storage container 3 is a drawer body.

  Therefore, it is possible to pull out and separate the granular material container 2 without removing it. For this reason, it becomes easy to perform operations such as replacing the liquid absorbent sheet 6 that has been saturated by absorbing liquid such as urine. Further, since the liquid absorbent sheet storage container 3 is a drawer, the liquid absorbent sheet 6 does not adhere to the bottom surface portion 23 of the granular material storage container 2, but the back surface side of the bottom surface portion 23 of the granular material storage container 2 ( Since the plurality of arc-shaped arch portions 29 are continuously formed on the side facing the liquid absorbent sheet 6, the liquid such as urine is efficiently transferred to the liquid absorbent sheet 6 side as described above. .

  Further, the front plate portion 31 has the same size as or larger than the size of the opening 25 formed in the granular material storage container 2. When the liquid absorbent sheet storage container 3 is stored in the granular material storage container 2, the granular material storage is performed. The opening 25 formed in the container 2 is configured to be closed. This prevents the urine odor absorbed by the liquid absorbent sheet 6 from leaking outside. Further, the bottom plate portion 33 is formed to have the same size as or larger than the size of the bottom surface portion 23 of the granular material storage container 2. As a result, the liquid absorbent sheet 6 accommodated in the liquid absorbent sheet container 3 can be used in a size that is the same as or larger than the size of the bottom surface part 23 of the granular material container 2. The liquid such as urine is surely dropped on the liquid absorbent sheet 6 and absorbed.

  In the animal toilet of the first embodiment, a cover 4 for restricting the entry / exit direction of animals is detachably attached. As shown in FIGS. 2 and 3, the cover 4 is a peripheral frame 41 having a substantially rectangular bottom. A wall 42 is erected on three sides of the peripheral frame 41, and an animal enters and exits the other side. A substantially U-shaped box in a plan view in which an opening 43 is formed, as in the case of the granular material storage container 2 and the liquid absorbent sheet storage container 3, polyethylene (PE), polypropylene (PP), polyethylene-terephthalate (PET) And other plastic materials such as polyolefin resin, and metal plates such as stainless steel. The peripheral frame 41 is substantially the same size as the upper end portion of the granular material storage container 2 and is formed in a shape that can be fitted to the upper end portion of the granular material storage container 2.

  By attaching the cover 4 in this way, it serves to prevent animals such as cats from entering and exiting from places other than the entrance / exit formed in the cover. Moreover, when a granular material is applied to feces and urine with a foot after excretion, it is possible to prevent the granular material from splashing outside. The height of the wall 42 prevents the granular material 5 from splashing outside when the animal applies the granular material 5 to the excrement after excretion, and also prevents the animal from entering and exiting from the entrance / exit. From the viewpoint of making it possible, it is preferably 10 cm or more, more preferably 10 to 40 cm.

  In the present embodiment, the cover 4 is configured to be fitted and installed on the upper part of the granular material storage container 2, but a configuration in which the cover 4 is not provided may be employed.

  The granular material 5 has a maximum liquid absorption amount of 0.3 to 4.0 times its own weight, and a liquid absorption amount in a short time of 0.1 to 1.5 times its own weight. A water-resistant silica gel having an absorption amount of 20% to 70% of the maximum liquid absorption amount and a liquid passage rate of 70% or more is preferable. The granular material 5 has a particle size of 4 to 10 mm, preferably 5 to 8 mm, and more preferably 6 to 8 mm. If the particle size is smaller than 4 mm, the gap between the granular materials becomes smaller, the surface area becomes larger, and the opening area of the opening portion 26 of the bottom surface portion 23 of the granular material storage container 2 needs to be reduced. A passage rate falls and much urine remains in the granular material storage container 2, and it becomes a cause which an odor generate | occur | produces in a short period of time. On the other hand, if it is larger than 10 mm, animals such as cats are disliked and cannot urinate. The moisture content is also 4 to 15%, preferably 5 to 10%. This is because if the moisture content is lower than 4%, the absorption rate increases and the liquid passage rate decreases.

  Since the liquid passage rate is increased by using such a granular material 5, no liquid such as urine remains on the bottom surface of the granular material storage container, and no odor is generated. Moreover, since it has absorptivity, a small amount of water droplets of urine is not left on the surface of the granular material, and it is hygienic and can maintain a smooth feeling. Furthermore, since the water | moisture content of feces can also be taken, since the smell of feces will also be reduced, it is preferable.

  Here, the maximum absorption amount is that after putting 100 g of granular materials into a mesh container of a size that does not overlap each other, soaking in physiological saline for 5 minutes, and then pulling up the container and removing excess water sufficiently The amount obtained by measuring the amount of liquid absorbed in the granular material. Similarly, the amount of liquid absorbed in a short period of time means that 100 g of granular materials are placed in a mesh-like container that does not overlap each other, soaked in physiological saline for 3 seconds, and then the container is lifted to remove excess moisture. This is an amount obtained by measuring the amount of liquid absorbed in the granular material after it is sufficiently cut. In addition, the passage rate is a container having a width of 20 cm, a depth of 20 cm, and a height of 5 cm and a bottom set to an opening ratio of 50% (thickness 5 mm, opening 3 × 5 mm), and a granular material is spread to a thickness of 25 mm, This is a value obtained by dropping 20 ml of physiological saline with a burette in 5 seconds and measuring the amount of liquid absorbed by the liquid absorbent sheet laid under the container.

  In addition, this granular material 5 is not limited to the above-mentioned thing, The outer diameter dimension formed by inorganic materials, such as resin, such as a polypropylene (PP), synthetic zeolite, natural zeolite, and a glass type, is 2 mm. Alternatively, conventional cat sand such as a cylindrical shape or a spherical shape of about 4 mm may be used.

As the liquid absorbent sheet 6, liquid absorbent sheets for animals such as nonwoven fabric, paper, cotton in sheet form, water absorbent resin, water absorbent material such as silica gel, pulverized pulp, etc. are used normally. A sheet can be used. Further, the liquid absorbent sheet 6 has an antibacterial and antibacterial part having both antibacterial and antibacterial properties, or has both an antibacterial part having antibacterial properties and a bacteriostatic part having antibacterial properties. It is also preferable. Since the liquid-absorbing sheet 6 has antibacterial and antibacterial properties, urine odor and decay can be prevented. Furthermore, it is preferable that the liquid absorbent sheet 6 is colored white so that the urine absorbing surface can be seen, or white so that the health condition of the animal can be grasped by the amount and color of urine. The urine absorption surface is a surface that absorbs liquid such as urine, and is a surface that receives liquid dropped from the bottom surface portion.
In addition, as for the liquid absorption sheet 6 used for the toilet for animals of this invention, that whose water retention amount is about 400 g / 2000 cm < ² > is preferable.

  In the first embodiment, as shown in FIG. 10, the liquid-absorbent sheet 6 includes a liquid-permeable surface layer 61, a liquid-impermeable back layer 62, and these liquid-permeable surface layers 61 and liquid-impermeable. It has the upper absorption layer 63 and the lower absorption layer 64 which have the liquid absorptivity sandwiched between the permeable back surface layer 62. The liquid-permeable surface layer 61 is white, and the liquid-impermeable back layer 62 is colored. The upper absorption layer 63 and the lower absorption layer 64 sandwich an antibacterial antibacterial part 67 in which the antibacterial part 65 and the antibacterial part 66 are formed in contact with each other. The upper absorbent layer 63 and the lower absorbent layer 64 both contain pulp and a superabsorbent resin. An upper tissue 68 is sandwiched between the upper absorbent layer 63 and the liquid permeable surface layer 61, and a lower tissue 69 is sandwiched between the lower absorbent layer 64 and the liquid impermeable back layer 62. Both the upper layer tissue 68 and the lower layer tissue 69 are white. The antibacterial part 65 is formed by containing an antibacterial property-imparting component such as a cationic surfactant type antibacterial agent “didecyldimethylammonium adipate”, and the antibacterial part 66 is, for example, pH control. It is formed by containing an antibacterial property-imparting component such as citric acid, which is highly safe as an agent.

  By using such a liquid absorbent sheet 6, it is possible to prevent the smell of urine and spoilage, so that the generation of bad odor can be suppressed and hygienic, so that the replacement time of the liquid absorbent sheet 6 can be extended. This is possible and more preferable.

  According to the animal toilet of the first embodiment having the above-described configuration, the animal toilet includes a container having a bottom portion made of liquid and a liquid-absorbing sheet storage container that stores a liquid-absorbing sheet that absorbs urine. A plurality of openings are formed in the bottom portion of the container, and a plurality of arc-shaped arch portions facing upward are continuously formed on the side of the bottom portion facing the liquid absorbent sheet. By providing the liquid guiding part, urine can be efficiently transferred to the liquid absorbing sheet. That is, the urine excreted by an animal such as a cat passes through the liquid-permeable bottom part and moves to the back side of the bottom part (the side facing the liquid-absorbing sheet), and the liquid induction formed on the back side of the bottom part It is gathered efficiently along the part and is dropped onto the liquid-absorbing sheet installed below and absorbed. Therefore, it is only necessary to replace the liquid absorbing sheet when cleaning the toilet, and the toilet can be easily cleaned.

  Also, by having a plurality of openings on the bottom surface of the container, urine and other liquids excreted by the animal will pass to the back side through the opening on the bottom surface and should not remain on the bottom surface of the granular material storage container. become. Moreover, the granular material accommodated on the bottom surface portion does not fall down through the opening. Further, the liquid absorbent sheet is disposed at a position facing the lower side of the bottom part of the granular material storage container with a distance therebetween, and the liquid absorbent sheet is not in contact with the bottom part of the container, and is therefore absorbed by the liquid absorbent sheet. Liquid such as urine does not return to the bottom. For this reason, when the granular material is stored in the container, there is no fear that the granular material is totally contaminated. Therefore, the number of times the granular material is replaced can be reduced, and the amount of garbage can be reduced without taking time and effort. it can.

  Next, a second embodiment of the animal toilet according to the present invention will be described.

FIG. 11 is an overall perspective view of an animal toilet provided with a granular material dropping tool in the first embodiment, and FIG. 12 is an exploded perspective view of the granular material dropping tool. In the following embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted. In these drawings, the dimensions are appropriately adjusted for easy understanding.

  The animal toilet of the second embodiment is provided with the granular material dropping tool 7 in the embodiment shown in FIG. 1, and the other components are the same. A description thereof will be omitted.

In the animal toilet of the second embodiment, the granular material dropping tool 7 is detachably installed at a position facing the opening of the cover 4.
Specifically, as shown in FIG. 11, the granular material dropping tool 7 is attached to and detached from the cover 4 in front of the granular material storage container 2 and the cover 4 (on the left hand side in the figure, on the side where animals enter and exit). It is attached in a form that can be freely. For example, in this embodiment, a pair of engagement holes 44 and 44 ′ are formed on the left and right of the front side of the wall body 42 of the cover 4 (on the left hand side in the figure, on the side where the animal enters and exits). A pair of protrusions 74 and 74 ′ are formed on the granular material removing member 71 (see FIG. 12), and the protrusions 74 and 74 ′ are attached by being fitted into the engagement holes 44 and 44 ′ of the cover 4. This attachment method is not limited to this.

  By having such a configuration, when an animal such as a cat enters or exits the toilet, it can be guided onto the granular material dropping tool 7, and the animal such as a cat can move to the granular material dropping tool 7 installed at the entrance of the opening. Since the animal walks up and down to enter and exit the animal toilet, particulate matter adhering to and around the crotch of the animal's toes when leaving the toilet after excretion is removed by the particulate dropper 7. Therefore, the particulate matter is not scattered throughout the room. Moreover, since it is a separate body from the toilet body, when cleaning the toilet, it is possible to easily take out and clean the particulate dropper main body, which is not cumbersome and labor is reduced.

  As shown in FIG. 12, the granular material dropping tool 7 includes a granular material removing member 71 and a granular material collecting container 72 that collects sand (granular material) dropped by the granular material removing member 71. The particulate matter collection container 72 is installed below the particulate matter removing member 71. The granular material dropper 7 is also made of a polyethylene resin (PE), polypropylene (PP), a polyolefin resin such as polyethylene-terephthalate (PET), or other plastic material, and a metal plate such as stainless steel, like the granular material container 2 and other members. Molded and processed.

  The granular material dropping tool 7 includes a granular material removing member having a mesh-like top plate and a granular material recovery container installed below the granular material removing member. A plurality of through holes 73a are formed in the top plate 73 at the bottom of the granular material removing member 71 and opened in a mesh shape. The shape of the through holes 73a is not limited to any other shape such as a circle, an ellipse, or a rectangle, and the arrangement thereof is also limited to any arrangement such as a mesh shape or a lattice shape. It is not something. Furthermore, when the animal such as a cat walks, the size may be not more than a size that does not cause the animal's feet to fall from the through-hole 73a and may be not less than the size of the granular material or the like, but is 5 to 15 mm. It is preferable. More preferably, it is about 10 mm.
