Cat litter product

Abstract

Litter compositions are provided comprising sodium bentonite and various fillers. These litter compositions have substantially the same clumpability properties as a composition consisting of only the sodium bentonite.

What is claimed is: 
     
         1 . A composition comprising:
 a blend of sodium bentonite and calcium bentonite,   wherein the calcium bentonite is coated with a coating comprising polytetrafluoroethylene (PTFE).   
     
     
         2 . The composition of  claim 1 , wherein the sodium bentonite has an average particle size of between 450 and 1000 μm and the calcium bentonite has an average particle size of between 650 and 2000 μm 
     
     
         3 . The composition of  claim 1 , wherein the calcium bentonite comprises 5% to 53% the blend. 
     
     
         4 . The composition of  claim 1 , wherein the calcium bentonite comprises 10% to 53% the blend. 
     
     
         5 . The composition of  claim 1 , wherein the calcium bentonite comprises 15% to 53% the blend. 
     
     
         6 . The composition of  claim 1 , wherein the composition comprises a clumping additive for increasing the clumping of the composition. 
     
     
         7 . The composition of  claim 1 , wherein the composition is a removably clumpable litter. 
     
     
         8 . The composition of  claim 1 , wherein less than 50% of the total external surface area of all particles in the blend are from sodium bentonite particles. 
     
     
         9 . The composition of  claim 1 , wherein the blend is a uniform blend. 
     
     
         10 . The composition of  claim 1 , wherein the blend comprises a fragrance coated on the sodium bentonite and/or the calcium bentonite. 
     
     
         11 . The composition of  claim 1 , wherein when the composition is exposed to urine has emissions of ammonia that are less than for a composition consisting of only the sodium bentonite.
