Animal toilet
An animal toilet includes a body portion, and a partition portion. The body portion has a bottom face part and a side face part, and is in a box shape. The partition portion is in a plate shape, and divides the inside of the body portion vertically. The partition portion has a through hole that allows urine to pass therethrough. The thickness of the partition portion in a surrounding part around the through hole is smaller than the thickness of the partition portion in a remaining part that is the part other than the surrounding part. The surrounding part around the through hole inclines downward toward the through hole.

a plate-shaped partition portion that has a through hole allowing urine to pass therethrough, and divides an inside of the body portion vertically, an inner surface of the through hole being in a cylindrical shape, wherein:
a first thickness that is a thickness of the partition portion in a surrounding part around the through hole is smaller than a second thickness that is a thickness of the partition portion in a remaining part, the remaining part being a part other than the surrounding part and surrounding the surrounding part,
an upper surface and a lower surface of the surrounding part are parallel to each other, each of the upper surface and the lower surface of the surrounding part inclining downward toward the through hole, and
the first thickness is half or less of the second thickness, the second thickness is a maximum thickness of the partition portion, and a third thickness that is a thickness of the through hole is less than the second thickness.
2. The animal toilet according to claim 1 ,
wherein an inclination angle of the surrounding part is between 10° and 50° inclusive.
3. The animal toilet according to claim 2 ,
wherein the inclination angle of the surrounding part is between 20° and 40° inclusive.
4. The animal toilet according to claim 1 ,
wherein the first thickness is equal to a minimum thickness of the partition portion.
5. The animal toilet according to claim 1 ,
wherein an outer diameter of the surrounding part around the through hole is 1.5 times or more of a diameter of the through hole.
6. The animal toilet according to claim 1 ,
wherein a shape of the through hole and a shape of an outline of the surrounding part are similar to each other in plan view.
7. The animal toilet according to claim 1 ,
wherein an area of the remaining part is larger than an area of the surrounding part in plan view.
8. The animal toilet according to claim 1 ,
wherein an entirety of a part of the partition portion other than the through hole has the first or second thickness.
9. The animal toilet according to claim 1 ,
wherein the partition portion is made of plastic.

wherein an outer diameter of the surrounding part is larger than a particle diameter of one of the plurality of grains that has a minimum particle diameter.
12. The animal toilet according to claim 1 ,
wherein an upper surface of the surrounding part is continuous with an upper surface of the remaining part.
13. The animal toilet according to claim 1 ,
wherein an upper surface of the surrounding part is not continuous with an upper surface of the remaining part.
14. The animal toilet according to claim 1 ,
wherein the partition portion has a plurality of the through holes, the surrounding part and the remaining part provided in between adjacent ones of the through holes.
15. The animal toilet according to claim 14 ,
wherein the partition portion has the second thickness at a midpoint of adjacent two of the through holes.
16. The animal toilet according to claim 1 ,
wherein the body portion has a projecting part that is provided so as to project from the side face part toward the inside of the body portion, and
the partition portion is placed on the projecting part.
17. The animal toilet according to claim 1 , further comprising:
a water-absorbing sheet that is disposed under the partition portion and absorbs the urine having passed through the through hole.
18. The animal toilet according to claim 17 , further comprising:
a drawer portion that houses the water-absorbing sheet,
wherein an opening is formed in the side face part of the body portion, and
