Cat litter product
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.
1. A composition comprising:
a blend comprising sodium bentonite and calcium bentonite,
wherein sodium bentonite comprises at least 47% of the total external surface area of the blend,
wherein the calcium bentonite comprises 5% to 53% of the total external surface area of the blend,
wherein 90% of the particles of the sodium bentonite have a particle size of 345 to 1695 μm, and
wherein 90% of the particles of the calcium bentonite have a particle size of 626 to 2000 μm.
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 10% to 53% the blend.
4. The composition of claim 1 , wherein the calcium bentonite comprises 15% to 53% the blend.
5. The composition of claim 1 , wherein the composition comprises a clumping additive for increasing the clumping of the composition.
6. The composition of claim 1 , wherein the composition is a removably clumpable litter.
7. 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.
8. The composition of claim 1 , wherein the blend is a uniform blend.
9. The composition of claim 1 , wherein the blend comprises a fragrance coated on the sodium bentonite and/or the calcium bentonite.
10. 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.
11. The composition of claim 1 , wherein the clump strength is at less 1.33 or better according to Standard Drop Method Test.
