Abstract: An animal self-grooming system incorporating a platform supporting horizontally and vertically oriented brushes or combs which is usable by an animal without human intervention is disclosed. The brushes or combs are positioned such that they support walk-by and stationary self-grooming respectively as well as massage. An animal attraction substance may be applied to the brushes or combs for animal self-grooming training. A material that promotes claw exercise may optionally be applied to the vertical and/or horizontal structural components of the disclosed device to incorporate a “scratching post” appliance within the animal self-grooming system context.

Abstract: A water-powered, self-cleaning rotary strainer for use in drawing water from a running stream. A perforated drum is rotatably mounted on a frame. Drum rotation is done by using moving water. A float is mounted on the frame to support the drum in a partially submerged condition. Water is withdrawn from the interior of the drum through a conduit as the drum rotates and debris is passed around the drum.
