An animal waste disposing assembly includes a base that has a top side, a bottom side and a peripheral edge extending between the top and bottom sides. The base has a threaded opening extending therethrough. A cylindrically shaped post is attached to and extends away from the bottom side. The post has an aperture extending therethrough that is aligned with the opening. The post has an outer threaded surface adapted for engaging a sewer line. A cylindrically shaped cap has a lower end, an upper end and a perimeter wall. The perimeter wall is threaded and the cap has a diameter generally equal to a diameter of the opening. The lower end may be removably extended into and threadably coupled to the opening. A peripheral lip is attached to and extends upwardly from the base. Feces may be positioned in the opening and ultimately the sewer line.
