Description

TECHNICAL FIELD

The present invention involves a cat scratcher-based attractant and amusement device capable of encouraging a domestic cat to employ a dedicated scratching surface rather than furniture, carpets and drapes and to maintain a cat's interest for prolonged periods of time in doing so.

BACKGROUND OF THE INVENTION

It is quite important for the health and well-being of a pet to not only feed it properly but also provide it with stimulating activities. Pets which become bored oftentimes become destructive not only of their surroundings but also themselves. Animals which are not appropriately stimulated can actually suffer adverse health effects and as a consequence. As such, proper pet stimulation should be a significant consideration for virtually all pet owners.

It is similarly well recognized that domestic cats crave scratching as part of their natural instinctive character. If a dedicated scratching surface is not provided, domestic cats will generally satisfy their need to scratch by turning to furniture, curtains and other articles which can be substantially damaged as a consequence. Often times, pet cats will not only climb over furniture, specifically upholstered chairs and sofas, but will use such furniture and carpeting to condition their claws through deliberate repeated clawing, pulling and tearing actions specifically with their forepaws. As noted, this clawing activity appears to be an irresistible natural impulse for cats and can be the source of great aggravation to pet owners.

However, the process of scratching is necessarily destructive as the surface must give to some extent to satisfy the cat. Correspondingly, the exposed surface is subject to degradation and once sufficiently worn, loses its appeal to the cat.

It is thus an object of the present invention to provide a cat scratcher having increased longevity that may occupy a cat for a relatively greater length of time.

It is a further object of the present invention to provide a cat scratcher that includes corrugate blocks that can be treated with an appropriate attractant to help stimulate the cat and encourage use of the cat scratcher.

It is still a further object of the present invention to provide a cat scratcher which maintains integrity over time to facilitate use by the cat.

These and further examples will be more readily apparent when considering the following disclosure and appended claims.

SUMMARY OF THE INVENTION

A cat scratcher comprising a frame of sidewalls encompassing a block of open-fluted cardboard and a planar back member with a removable panel. Removing the panel exposes a surface of the block of open-fluted cardboard. The panel may be defined by perforations in the planar back member.

There has been broadly outlined more important features of the invention in the summary above and in order that the detailed description which follows may be better understood, and in order that the present contribution to the art may be appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form additional subject matter of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based readily may be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important therefore, that claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

Certain terminology and the derivations thereof may be used in the following description for convenience and reference only, and will not be limiting. For example, words such as “upward,” “downward,” “left,” and “right” refer to directions in the drawings to which reference is made unless otherwise stated.

Reference in the singular tense include the plural and vice versa, unless otherwise noted.

In turning first to FIG. 1, an embodiment of this disclosure is cat scratcher 10 that includes a substantially rectangular box 12 ideally composed of cardboard bent and configured into the shape as illustrated and defined by four sidewalls 14, 16, 18 and 20. A block 22 of open-fluted corrugated cardboard is encompassed and is affixed to the sidewalls so that a front surface is exposed and accessible to the cat. Sidewalls 14, 16, 18 and 20 form a frame to support and contain block 22, helping maintain its integrity during use over time. Hanger 24 has an aperture 26 configured to fit over a door handle so that cat scratcher 10 can be hung if desired and is shown in this embodiment with a decorative “cat head” profile but other suitable shapes, such as a hook, are also within the scope of this disclosure. As depicted in FIG. 2, back 28 of box 12 is provided as a planar sheet extending between and secured to the respective opposing sidewalls. Back 28 is preferably of cardboard and has perforated outline 30 that allows panel 32 to be removed to expose a rear surface of block 22 according to FIG. 3. As will be appreciated, removing panel 32 exposes a fresh surface after the front becomes too worn to satisfy the cat and thereby extends the useful working life of cat scratcher 10. In some embodiments, any or all of the sidewalls 14, 16, 18 and 20, hanger 24 and back 28 may be formed from a single sheet of material.

It is noted that corrugated cardboard block 22 can be fabricated pursuant to the teachings of commonly-owned U.S. Pat. No. 10,111,406, the disclosure of which is incorporated by reference. Specifically, FIGS. 4 and 5 depict the present invention as it applies to block 22 of corrugated cardboard. As is typically the case, corrugated cardboard comprises a plurality of corrugated subparts, specifically, corrugated sheet 34 having peaks 36 and corresponding valleys 38 and planar sheets of kraft paper 40 and 42 separating each corrugated sheet. Beads of adhesive 44 are applied to the kraft paper such that when corrugated sheet 34 is positioned between opposing sheets of kraft paper 40 and 42, cardboard block 22 is fabricated as a singular, monolithic unit. Generally, starch or dextrin-based adhesives are employed as they are non-toxic and thus pose no health risk to an engaging cat.

In the fabrication of prior cardboard-based scratchers, a common adhesive is employed to glue corrugated and planar sheets together and, if desired, ground catnip or silvervine leaves are sprinkled onto the flutes of the finished cardboard block. As the catnip or silvervine is readily available to the pet, it is quickly dissipated and provides the scratcher with no long-term stimulating effects. As a solution to this deficiency inherent in prior scratchers, the present invention employs a catnip or silvervine hydrosol in a suitable aqueous-based adhesive to create beads 44. It has been found that, in doing so, the integrity of the adhesive is not compromised and yet the desired stimulating effects are available for virtually the entire life of the scratcher.

Furthermore, catnip or silvervine hydrosol, alone, or with chopped catnip leaves can be sprayed onto the surface of block 22 employing, for example, a spray gun to provide catnip or silvervine within the flutes created by corrugated sheets 34. This further enhances the stimulating effects of the scratcher noting that the catnip or silvervine hydrosol penetrates deeply within the flutes and, being a liquid, is absorbed by kraft paper sheets 40 and 42 as well as corrugated sheet 34. Solids, in the nature of chopped catnip or silvervine leaves and/or catnip or silvervine biomass can be included with the catnip or silvervine hydrosol to vary the viscosity of the spray to prevent the spray from passing through block 22 without residing within the flutes as desired employing a proprietary blend of catnip hyrdosol and catnip biomass.

The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. Notably, as will be appreciated, the techniques of this disclosure provide benefits including efficiency in shipping and increased ability for the cat to relax or lounge in a variety of position, as well as the ability to scratch from different positions, such as standing up or laying on their side(s), along with other advantages. While there is provided herein a full and complete disclosure of the preferred embodiments of the invention, it is not desired to limit the invention to the exact construction, dimensions, relationships, or operations as described. Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed as suitable without departing from the true spirit and scope of the invention. Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like. Therefore, the above description and illustration should not be considered as limiting the scope of the invention, which is defined by the appended claims.
