Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
22 words
An animal litter for absorbing animal wastes comprising: an absorptive material; and non-enteric bacteria, whereby the non-enteric bacteria decomposes the animal waste.
Claim 2
Dependent Claim
22 words
An animal litter for absorbing animal wastes comprising: an absorptive material; and non-enteric bacteria, whereby the non-enteric bacteria decomposes the animal waste.
Claim 3
Dependent Claim
15 words
The animal litter of claim 1, further including a fragrance associated with the absorptive material.
Claim 4
Dependent Claim
17 words
The animal litter of claim 2, wherein the fragrance is cedar oil applied to the absorptive material.
Claim 5
Dependent Claim
18 words
The animal litter of claim 1, further including a plurality of cedar needles mixed with the absorptive material.
Claim 6
Dependent Claim
43 words
The animal litter of claim 1, wherein the absorptive material has pores and is selected from the group consisting of clays, diatomateous earths, Fuller's earths, and betonites, that are low in bulk density and have the ability to absorb liquids into their pores.
Claim 7
Dependent Claim
13 words
The animal litter of claim 1, wherein the absorptive material is Georgia clay.
Claim 8
Dependent Claim
13 words
The animal litter of claim 1, wherein the non-enteric bacteria is non-enteric bacteria.
Claim 9
Dependent Claim
19 words
The animal litter of claim 7, further including enzymes which are products of growth of the non-enteric bacillus bacteria.
Claim 10
Dependent Claim
14 words
The animal litter of claim 8, wherein the enzymes include protease, amylase, and pacreatin.
Claim 11
Independent Claim
31 words
A method for making an animal litter for absorbing animal wastes comprising the steps of: forming particles of an absorptive material; and combining the particles of absorptive material with non-enteric bacteria.
Claim 12
Independent Claim
31 words
A method for making an animal litter for absorbing animal wastes comprising the steps of: forming particles of an absorptive material; and combining the particles of absorptive material with non-enteric bacteria.
Claim 13
Dependent Claim
16 words
The method of claim 10, including the step of associating a fragrance with the absorptive material.
Claim 14
Dependent Claim
23 words
The method of claim 11, wherein the fragrance is associated with the absorptive material by applying a liquid fragrance to the absorptive material.
Claim 15
Dependent Claim
28 words
The method of claim 12, including the step of utilizing cedar oil as the fragrance and applying the fragrance by spraying the cedar oil upon the absorptive material.
Claim 16
Dependent Claim
19 words
The method of claim 10, including the step of mixing a plurality of cedar needles with the absorptive material.
Claim 17
Dependent Claim
45 words
The method of claim 10, wherein the absorptive material which is utilized has pores and is selected from the group consisting of clays, diatomateous earths, Fuller's earths, and betonites, that are low in bulk density and have the ability to absorb liquids into their pores.
Claim 18
Dependent Claim
14 words
The method of claim 10, wherein Georgia clay is utilized as the absorptive material.
Claim 19
Dependent Claim
15 words
The method of claim 10, wherein non-enteric bacillus bacteria is utilized as the non-enteric bacteria.
Claim 20
Dependent Claim
22 words
The method of claim 17, wherein enzymes, which are products of growth of the non-enteric bacteria, are added to the absorptive material.
Claim 21
Dependent Claim
13 words
The method of claim 18, wherein the enzymes include protease, amylase and pacreatin.
