A mat or other object for attenuating reflective spray during use of a urinal comprises a urine impingement region that includes a plurality of upstanding, flexible bristles. In one embodiment, each of the bristles: has an appropriate thickness and flexibility configured to flex when struck by a typical stream of urine, wherein adjacent bristles are separated from one another by a distance such that the typical stream of urine contacting a bristle and causing it to flex will also contact at least two adjacent bristles and cause them to flex as well; has a thickness and a height, wherein the thickness of each is less than one fifth of its height, and further wherein each bristle has at least three adjacent bristles within a distance of two times its thickness from it; is elongated, and the bristles are configured densely enough that an imaginary circle having a radius equal to a stream of urine's mean radius, centered on a given bristle, and drawn on the upper surface will include at least three other bristles within its boundary; or any combination of these. In some embodiments, the plurality of bristles that compose a urine retention region has an ordered arrangement, while in others plurality of bristles has a disordered arrangement.
