Abstract: A main body (22) has a downwardly-directed outlet opening (28) and a forwardly-directed inlet opening (30). A vertical wall (34) depends downwardly from opposite sidewalls (26) of body (22), is spaced rearwardly from inlet opening (30), and engages the inner vertical surface (8) of toilet bowl rim (6). A sloping horizontal wall (36) extends forwardly from the top edge of wall (34). A flexible vertical leg (38, 40) depends downwardly from the front of wall (36) and engages the outer vertical surface (10) of rim (6). Rim (6) is securely gripped between wall (34) and leg (38, 40). Body (22) preferably has a top wall (42) and a top lip (44) that help to form a moisture catching recess (46) when the attachment (20, 20') is upside down. A funnel-like portion (32, 32') extends down into toilet bowl (4) and may have a cutout (52) to make water in bowl (4) visible to a user.
