Toilet device for cats

Abstract

A feces and urine disposal device for cats includes a support structure having parallel, vertically extending wall members, a bottom chamber, and an elevated relief area between the opposing wall members and above the bottom chamber. The relief area includes a pair of longitudinal channels disposed in spaced, parallel relation to one another and an open longitudinal gap between the channels and communicating with the bottom chamber. In use, a cat stands in the relief area with the left paws in one channel and the right paws in the opposite channel so that the cat is straddling the gap. When the cat relieves itself, feces and urine pass through the gap and into a removable trough positioned in the bottom chamber or directly into a toilet bowl. Cat litter or another odor absorbing or containing substance can be placed in the trough, as well as the relief area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(14) Referring to the several views of the drawings, the feces and urine disposal device for cats (hereinafter cat toilet device) of the present invention is shown and generally indicated as 10.

(15) Referring initially to FIGS. 1-4, a first embodiment of the cat toilet device 10 includes a support structure 12 having parallel, vertically extending wall members 14, 16, a bottom chamber 18, and an elevated relief structure 20 between the opposing wall members 14, 16 and above the bottom chamber 18. The relief structure 20 includes a pair of longitudinal channels 22, 24 disposed in spaced, parallel relation to one another and an open longitudinal gap 26 between the channels 22, 24 and communicating with the bottom chamber 18. One or more steps 28 are provided for allowing a cat to climb the support structure 12 and pass through an entry 27 between the wall members 14, 16 in order to reach the relief structure 20. Slots 29 are provided at the entry for insertion of one or more shims 70 (FIG. 11) in order to narrow the space between the wall members as part of the training process, as described further herein.

(16) In use, a cat stands on the relief structure 20 with the left paws in one channel and the right paws in the opposite channel so that the cat is straddling the gap 26. When the cat relieves itself, feces and urine pass through the gap 26 and into a removable trough 30 that is positioned in the bottom chamber 18 and directly below the gap 26. The trough 30 may be filled at least partially with any kind of cat litter, sand, or saw dust. Alternatively, the trough 30 may be partially filled with water. When water is used, a few drops of oil can be placed on the top surface of the water to create a barrier that helps to prevent release of odors of the feces and urine from below the surface of the water.

(17) Referring to FIGS. 5A-6, the cat toilet device 10 may include various size training inserts 32a, 32b and 32c for gradually training the cat to utilize the device 10 as described above, wherein the feces and urine pass through the gap 26. As shown in FIG. 5A, one embodiment of the training insert 32a includes a platform 34 that extends the width of the insert 32a. This embodiment of the training insert 32a is ideally used when first introducing a cat to the device 10, wherein the insert 32a has the completely closed platform 34 that can be covered with cat litter or other substance so that the device 10 most closely mimics a traditional litter box. FIGS. 5B and 5C show additional embodiments of the training insert 32b and 32c each including a gap 36 extending the length of the platform 34, and wherein the gap 36 in insert 32c is wider than the gap 36 in the insert 32b. When training a cat to use the cat toilet device 10, training inserts 32a-32c are progressively replaced on the device 10 so the cat can gradually transition into using the cat toilet device 10 without a training insert. Cat litter, sand, saw dust or another granular substance would normally be filled in the longitudinal channels 22, 24 for the cat to stand in while relieving itself. Eventually, some cats may become completely acclimated to use of the device at which point use of cat litter, saw dust, etc. in the channels 22, 24 may no longer be necessary. The top surfaces of the steps 28 contain a number of square cut-out notches to assist with removal of cat litter, saw dust, etc. when the cat exits the relief structure 20.

(18) Each training insert 32a-32c includes oppositely disposed lips 38 sized and configured to engage the longitudinal gap 26 between the channels 22, 24 of the relief structure 20 so that the training insert remains in place during use. As shown in FIG. 6, the training insert 32a, 32b or 32c is lowered between vertically extending wall members 14, 16 and placed against the relief structure 20. Oppositely disposed tabs 40 on each of the embodiments of the training inserts 32a-32c, allow the amount of litter being filled on top of the training insert 32a, 32b or 32c to cover the training strips, which allows the device 10 to most closely mimic a traditional litter box, therefore aiding the training process.

(19) Referring to FIGS. 7-10, a second embodiment of the cat toilet device 10 is shown and is provided for use in combination with a standard bathroom toilet. This embodiment of the cat toilet device 10 includes a support structure 42 having parallel, vertically extending wall members 44, 46, a bottom chamber 48, and an elevated relief structure 50 between the opposing wall members 44, 46 and above the bottom chamber 48. The relief structure 50 includes a pair of longitudinal channels 52, 54 disposed in spaced, parallel relation to one another and an open longitudinal gap 56 between the channels 52, 54 and communicating with the bottom chamber 48. The channels 52 and 54 are intended be filled at least partially with a commercially available flushable cat litter. One or more stairs 58 are provided for climbing the support structure 12 to reach the relief structure 20. Oppositely disposed toilet bowl engaging members 60 are in communication with the relief structure 50 and are provided for frictionally engaging the inner sides of a toilet bowl rim in order to support the cat toilet device 10 on the bathroom toilet. An entry 57 is provided at one end of the support structure 42. A window 62 is provided at the opposite end to permit additional head room (between the device 10 and the toilet bowl tank) for longer cats while relieving themselves. A step 64 is positioned above the window 62 for the cat to step onto after relieving itself in order to exit the device 10 and subsequently step onto the toilet bowl tank or other structure.

(20) This second embodiment of the cat toilet device 10 may also be used in combination with a support base 68 and removable trough 66 that slides into the support base 68. The support base 68 allows for the option of placing the cat toilet device 10 on a floor surface instead of a bathroom toilet. In this instance, the support structure 42 is seated on top of the support base 68 which rests on the floor surface. The removable trough 66 is sized and configured to slide into the support base 68, as seen in FIG. 7, so that the trough is positioned directed below the relief structure 50 and the open longitudinal gap 56 when the support structure 42 is seated on top of the support base 68. In use, the trough 66 can be easily pulled out from the support base 68 for cleaning. The trough 66 may be filled at least partially with cat litter, sand or sawdust. Alternatively, the trough 66 can be partially filled with water. When water is used in the trough 66, a few drops of oil can be placed on the top surface of the water to create a barrier that helps to prevent release of odors of the feces and urine from below the surface of the water.

(21) Referring to FIG. 11, a single one of a pair of shims is shown. Each shim 70 is sized and configured for insertion into slots 29 on the inner facing surfaces of the vertically extending wall members 14, 16 of the first embodiment and 44, 46 of the second embodiment. When in place, the shims 70 serve to confine the cat in a more narrow space in order to more likely ensure that the cat will relieve itself in the open longitudinal gap 26 or 56. During the training process, the shims 70 are symmetrically repositioned on each side to gradually train the cat to be centered above the longitudinal gap 26 or 56 when relieving itself.

(22) While the present invention has been shown and described in accordance with a preferred and practical embodiment thereof, it is recognized that departures from the instant disclosure are contemplated within the spirit and scope of the present invention.
