Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 81 words
An animal litter consisting essentially of a chlorophyll-containing agent from the class consisting of alfalfa, algae, broom grass and timothy grass, and a relatively high density cellulosic agent consisting of corncob grits, said chlorophyll-containing agent and said grits being physically intermixed in a dry, discrete state, said intermixture being free of chemical agents, compounds, and preparations, said grits constituting between approximately 50% to 70% by weight of the litter and said chlorophyll-containing agent constituting approximately 50% to 30% of the litter.
Claim 2
Dependent Claim 81 words
An animal litter consisting essentially of a chlorophyll-containing agent from the class consisting of alfalfa, algae, broom grass and timothy grass, and a relatively high density cellulosic agent consisting of corncob grits, said chlorophyll-containing agent and said grits being physically intermixed in a dry, discrete state, said intermixture being free of chemical agents, compounds, and preparations, said grits constituting between approximately 50% to 70% by weight of the litter and said chlorophyll-containing agent constituting approximately 50% to 30% of the litter.
Claim 3
Dependent Claim 18 words
An animal litter as defined in claim 1 and further characterized by the chlorophyll-containing agent being pelletized alfalfa.
Claim 4
Dependent Claim 24 words
