Abstract
ABSTRACT
An animal litter composition containing a blend of attapulgite and water swellable bentonite clays. The clays are present in a proportion which enables the animal litter to absorb animal dross and form clumps. The clumps are stable enough to enable physical separation from the non-wetted portions of the litter yet are capable of being broken down in a flush toilet toallow for disposition of the clumps by flushing down the toilet. A method for using the animal litter composition includes the steps of collecting liquid animal dross on a bed of the litter, allowing the litter to absorb the liquid and form clumps, physically separating the clumps from the non-clumped litter and flushing the clumps down a toilet.

Description
- 2 ~ 7 ~
Field ~ the Inv~ntion The present invention relates to a clay based absorbent con~position for 5 animal dross and its method ~or use.
Back~und ~ the Invention One o~ the problems faced by owners of such pets as cats is the 10 containment and removal of animal excrement. Generally this is achieved by providing a receptacle for the pet to use when perfor~ning its eliminative bodily functions and training the pet to use the receptacle. In order to minimize the associated odours and to reduce the possibilil~ o~ urine and fecal matter adhering to the pet's paws to be tracked throughout the owIIer's 15 residence, most pet owners place a material referred to as "pet litter" in the bottom o~ the receptacles. Accordingly the receptacles for pet waste are generally known by the phrase "litter boxes".
Prior animal litter has generally been made from various types 20 of clay as well as ot~er materials. Clay is a good material for animal litter as it has good sorptive qualities and is reasonably effective in controlling odours.
A problem with the earlier type of ~et litter products is that they eventually will release offensive odours once a certain amount of urine has been absorbed. As there is no simple way to separate the portion of these prior 25 litters which have absorbed urine from the remaining litter, once the odour from the litter becornes intolerable, the owner usually discards all of the pet litter and replaces it with new pet litter.
Recently some improved pet litter products have been 30 introduced into the marketplace which have the desirable quality of agglomerating in the presence of moistllre. When a pet urinates on these pet litter products, the urine causes the litter to agglomerate into clumps. With these more recent pet litter products it is relatively simple to identify the urine contaminated regions as these will be the clumps. Ideally the clumps 35 are stable enough to allow mechanical separation from the uncontaminated litter with a simple tool such as a slotted scooper.
Unfortunately the agglornerating type pet litter products available heretofore do not exhibit the optimum degree of agglomeration.
40 Sonne of the products form clumps which are relatively so~t and which tend to crumble upon drying. The disadvantage with these "soft clump" litters is that if the pet owner does not remove the clumps ~rorn the litter box within 12 to 24 hours, the clumps may be too soft for removal and will crumble if disturbed.
a~5 Other o~ the agglomerating type pet litters ~orm clumps which are too hard to enable the clumps to be flushed down a toilet into a sanitary sewer system. This is an inconvenience to many pet owners who keep litter 2 1~ 7 ~
boxes in their bathrooms and ws)uld prefer to flush animal excrement down the toilet rather than throwing it into the ordinary household garbage receptacle.
For the sake of completeness it should be pointed out that none of the agglomerating type pet litter products are recommended for use with septic systems.
The terms "liquid dross" and "liquid animal dross" are used below to refer to liquid animal excretions, particularly urine.
It is an object of the present invention to provide a pet litter formulation that agglomerates upon wetting into clumps which are still handleable after 24 hours but which will break down in a flush toilet to enable ~lushing without blocking of the toilet or associated plumbing.
S~mmary of t~Inventi~n An animal litter composition comprising a blend of attapulgite and water swellable bentonite clays, said clays being present in a proportion which enables said litter to absorb animal dross and form clumps which are stable enough to enable physical separation from the non-wetted portions of said litter yet which will break down in a flush toilet to enable said clumps tobe flushed down said flush toilet without blocking said flush toilet or its associated plumbing.
A method for collection and discarding liquid animal dross, said method comprising the steps of:
1. collecting said liquid animal dross in a bed of animal litter comprising a blend of attapulgite and water swellable bentonite clays, said clays being present in a proportion which enables said litter to absorb said liquid animal dross and form clu~mps which are stable enough to enable physical separation from the non-wetted portions of said litter yet which will break down in a flush toilet to enable said clumps to be flushed down said flush toilet without blocking said flush toilet or its associated plumbing;
2. allowing said clay to absorb said liquid animal dross and agglomerate into clumps having sufficient cohesion to enable said clumps to be physically separated from the non-wetted remainder of said litter;
2 Z~ 8 3. physically separating said clumps from said non-wetted remainder of said animal litter; and 4. placing said clumps in a flush toilet and flushing said toile~.
Description of D~a~ving The invention will now be described in more detail with 10 reference to the accompanying drawing in which:
Figure 1 is a partially cut away perspective view of a receptacle containing the animal litter composition of the present invention.
15 Detailed nescription of P~eferred Embodlm~nts of ~e Invention In this disclosure the expression "water swellable bentonite clays" is used to refer to those montmorillonite mineral containing clays which exhibit a significant increase in size on the addition of water. An 20 example of this type of clay is westerm bentonite which is primarily found in eastern Wyoming in the United S-tates. Other examples include sodium bentonite and montmorillonite clays.
The expression "attapulgite clavs" is used herein to refer to clays 25 containing the mineral attapulgite. Among the various suitable grades of attapulgite clay are those found in the southeastern United States. Sepiolite may be an alternative.
It has been found that the degree of clurn~ing and stability of 3Q clumps exhibited by the above clays will vary depending upon the fineness of the clay, with the finer clays exhibiting more clumping than coarser clays.
There are however other considerations beyond clumping which must be weighed in selecting the appropriate fineness or particle size of the clays. In general cats, the type of pet most likely to use a litter box, prefer a litter having 35 a sandy texture as opposed to either a dusty or gravelly texture. Furthermorewhen selecting the fineness of the clay it should be borne in the mind that very fine clays are likely to become and remain airborne thereby creating a dusting problem. Also very fine clays tend to adhere to the pet's paws and are therefore more likely to be transported away frorn the litter box by the pet's 40 paws to be deposited on the floor and furniture on which the pet travels.
Ideally at least 90% of the clay should have a particle size of greater than 60 mesh (Tyler Series) with a rnaximum particle size on the 2 ~
order of 18 mesh. Although not as desirable as the particle size range mentioned above, it is expected that suitable product could be prepared with clay having a particle size ranging ~rom 6 mesh to 100 mesh with no more than 10% of the clay being outside of this range.
As a practical matter, regardless of how small a fraction of the clay used in a product is finer than 100 mesh, abrasion of the clay particles against each other during packaging and shipping will generally result in the presence of a small fraction of sub 100 mesh sized particles. Accordingly the 10 particle sizing indicated herein is intended to apply to the product as blended.
The best results are obtained with compositions comprising from 25% to 50% sodium bentonite and the balance attapulgite type clay.
Possibly as little as 10% bentonite might be used in the formulation or as 15 much as 65%.
Reference is now made to Figure 1. Figure 1 shows a receptacle 10 having a base 12 from which upwardly extend sides 14. The receptacle is filled with an animal litter 16 having a composition as described above. The 20 animal litter 16 has an exposed upper surface 18.
In use, an animal would typically stand on the upper surface 18 of the animal litter 16 and deposit liquid animal dross on the upper surface 18 for example, at the region indicated by reference 20. The liquid animal dross 25 would be absorbed by the animal litter in 16 in the region 20 and would agglomerate to form a clump as shown at 22.
Periodically the person in charge of maintaining i:he litter receptacle would remove the cl~mps 22 and any solid dross ~rom the 30 remaining litter lG. ~/arious implements might be used to remove the clumps 22 such as the slotted scooper ordinarily used by ~nimal owners to rernove solid clross from animal litter recept~cles. Once the clumps 22 are removed they may be deposited in a flush toilet and the toilet flushed to break up the clumps and enable them to flow into a sanitary sewer system.
The range of compositions described above will agglomerate strongly enough to form clumps having sufficient stability to enable physical separation from the remaining or non-wette~ litter even if left in the litter receptacle for prolonged periods of time, on the order of several days.
a~o Nevertheless, the range of compositions described above will break down or disperse when subject to the turbulent action of a flushing toilet to enable them to pass through the toilet and its associated plumbing without causing blockages of the toilet or its associated plumbing.
