Abstract: An animal repelling device is disclosed that may include a first mounting bracket and a second mounting bracket, each of which includes an upper section and a lower section. The upper section may include a vertical tab, a notch formed in the vertical tab, and ribs coupled to opposing sides of the vertical tab. The lower section may include a foot coupled to a sidewall, the sidewall comprising a curved inner surface configured to mateably couple with a fence. A roller may be disposed between, be rotatably coupled to, and extend axially between, the first mounting bracket and the second mounting bracket, the roller comprising an aligner that biases the roller back to an initial at rest position. An attachment clip may be releasably coupled to the notch of the vertical tab.

Abstract: An apparatus for repelling animals which is attachable to the top of any external barrier. The apparatus has an elongated hollow roller with an opening on each of its two ends; an end cap, with an aperture for receiving an axle, seated in a water-tight manner into each end of the roller; and a mounting member having an upper section with one or more axle projecting from it wherein the axles are adapted to insert into the aperture of the end cap and permit rotation of the roller and also having a lower section adapted to attach to an external structure. Noise-producing articles may be inserted into the hollow of the roller such that, as the roller is rotated, the movement of the articles within emit noise.
