  • Patent number: 6899059
    Abstract: A catnip-filled toy (10) which may be caused to roll, spin, rock, wobble, and slide when manipulated by the paw of a cat. The device (10) has a convex hub (12). Extending axially from the hub (I 2) are two hollow reservoirs (14) that may be filled with catnip (24). The convex hub (12) and catnip reservoirs (14) are circular in shape when seen in side elevation from an end view, so as to allow the device (10) to roll freely upon any smooth surface (30). The hub is larger in circumference than the reservoirs for continuous rolling of the toy on the hub. In the preferred embodiment of the device (10), the reservoirs (14) are elongated axially beyond a hemispherical shape. The catnip reservoirs (14) have openings (20) through which the catnip (24) may be filled, emptied, and refilled and have a plurality of small holes (22) through which the scent of the catnip (24) inside may emanate outside. The holes (22) are small enough to substantially contain finely cut catnip (24).

  • Patent number: 6672253
    Abstract: A dog toy (10) comprising a gyroflier disk (12) having a convex upper surface (22), a concave lower surface (24), and a circular rim around the circumference (26). Through the radial center of the disk (12) is an aperture (14). Inserted vertically into the aperture (14) is a short length of rope (16). The top end of the rope (16) is tied in a knot (18) that is positioned close to, and above, the upper surface (22) of the disk (12). The lower end of the rope (16) is tied in a knot (20) that is positioned close to, and below, the lower surface (22) of the disk (12). The lower knot (20) is large enough to cause the lower edge of the circumferential rim (26) to be positioned sufficiently above a relatively flat surface upon which the toy (10) rests that a dog may be able to insert its mouth under the rim (26) in order to pick up the toy (10). If the toy (10) is at rest on the ground or other relatively flat surface, the dog may pick it up by grabbing the upper knot (18) in its mouth.

  • Patent number: 6609944
    Abstract: A ball toy 10 intended for use by pets that is molded of a flexible, resilient material, containing a hollow cavity inside 22. Attached to the hollow cavity is a squeaker 20. The squeaker 20 is activated by air rushing through it, into and out of the hollow cavity within the ball, as the ball 10 is squeezed and released. The ball. 10 is essentially round, allowing it to roll freely and easily in any direction. The ball 10 has features molded in relief on its outer surface 12 which resemble the face 14, legs 16, and tail 18 of an animal. The protruding features 14, 16, 18 cause the ball 10 to roll in a slightly erratic manner and may cause a light pitter-patter sound when the ball 10 rolled on a smooth surface, thus creating a resemblance to a small scurrying animal.

  • Patent number: 6601538
    Abstract: A new toy 10 for pets comprising a plurality of strips 12 each terminating in an end 16 that may be grabbed or bitten by the pet. The strips 12 are connected to a common junction 14 in such a manner that said strips 12 extend alternately from said junction 14 in opposite directions with some space in between the strips. All the strips 12 are convoluted or coiled about a common circular path. The common circular path forms a complete circle so that the toy 10 may roll freely with the coiled strips 12 in contact with the floor or other smooth surface upon which the toy 10 is used. The coiled strips 12 form a circular opening into which the pet may insert its paw in order to flip, lift, or scoop up the toy.

  • Publication number: 20020174838
    Abstract: A catnip-filled toy (10) for cats which may be caused to roll, spin around, wobble, and slide when manipulated by the paw of a cat. The device (10) has a central hub (12) which is convex in shape. Extending horizontally from the central hub (12) are two hollow reservoirs (14) which may be filled with catnip (24). The central hub (12) and catnip reservoirs (14) are circular in shape when seen in side elevation from an end view, so as to allow the device to roll freely upon any smooth surface. The catnip reservoirs (14) have openings (20) through which the catnip (24) may be filled, emptied, and refilled and have a plurality of small holes (22) through which the scent of the catnip (24) inside may emanate outside. The catnip reservoirs (14) are attached by screwing together and may be detached by unscrewing. An alternative embodiment may include yarn (232), feathers, or other soft material extending from and attached to the outer ends of the catnip reservoirs (14).

  • Publication number: 20010029904
    Abstract: A toy for pets (10) having a central hub (12) which is convex in shape. A plurality of appendages (14) are immovably connected to the central hub (12) and radiate from it in a single plane. Each appendage (14) has a knob (16) immovably connected at its outer end. The knobs (16) are convex in shape and are smaller in size than the hub (12). When manipulated by the paw of a pet, the device (10) can be made to spin or slide across a smooth surface (18) such as a floor, with the central hub (12) remaining in contact with the surface (18). The convex shape of the central hub (12) minimizes contact with the surface (18) and also provides a pivot point for the device (10) to rotate upon the surface (18). The appendages (14) and knobs (16) may be gnawed or chewed by the pet, grasped by the paws of the pet, or gripped by the mouth of the pet in order to carry the device (10).

  • Patent number: 5695086
    Abstract: A closure device (10) for pet food cans comprising a central cover member (12) and an outer cover member (14) which are integrated into the shape of a pet having protruding features (16), said protruding features providing a means of prying the device. Extending downwardly from the cover members (12 and 14) are a plurality of concentric annular bands (18), each having a bead or rib (20) extending inwardly from the inner surface.

  • Patent number: 5269256
    Abstract: An amusement device (10) intended for use by cats and other pets, which can be easily caused to move in sliding, rolling, or somersaulting motions, or other lively motions, through manipulation with the paw. The device (10) comprises a circular ring formed of a circumferential band (11) which has a plurality of elevational undulations having bases (13) and peaks (12) and a number of upwardly projecting shapes (14) which can be easily gnawed or bitten by the pet and grasped by the mouth of the pet.

  • Patent number: 5269716
    Abstract: A rotating flying toy comprising a circular airfoil (12) and a plurality of radial airfoils (13). Said radial airfoils (13) extend, at a uniform angle, from a central hub (14), which is elevated in profile above the circular airfoil (12). When tossed through the air in different specific ways, the device performs various unique aerodynamic maneuvers involving its tendency to roll over in a predictable manner, during flight.
