International Classification:

A01K 2900

US Classification:

Abstract:

A window mounted, ventilated, litter unit for installation on the outer wall of a house, to be used with conventional horizontal or vertical slide windows. A frame is constructed of square, thin wall steel tubing and has walls made of acrylic to allow sunlight within while keeping a cat safe. A swinging access door is provided at the window opening. The floor of the litter unit has a screen of perforated material which allows for the ventilation of litter which is maintained in a litter pan below the floor, and for litter tracked onto the floor to fall through the floor into the litter pan. The litter pan is easily removed from the bottom of the litter unit for outdoor cleaning. The rear of the litter unit has an upper support portion as part of the unit rear wall; the entire rear wall is dimensioned to completely surround a window opening so the invention may be used with windows that slide vertically or horizontally, without need of altering the litter unit or the window in any way.

Abstract:

An exercise device has first and second components with a hinge coupling the proximal ends of the components. The first component has a cone shaped distal region, a semi-cylindrical shaped proximal region, and a generally flat intermediate region. A recess is formed between the distal region and the proximal end. The second component has a thin disc-shaped distal region, a semi-cylindrical proximal region, and a generally flat intermediate region. The second component is positionable within the recess of the first component. An enlarged annular collar has a first half on the first component between the intermediate and proximal regions and a second half on the second component between the distal and proximal regions and has a radius of curvature greater than the radius of curvature of the proximal regions. A spring urges the first and second components into the open orientation during use.
