Results of Cat Litter Clumping Comparison

Despite all the dust and weight, I have to admit, the clay litter clumped the best. The clump-ability --- ability for the litter to clump into a hard, easy-to-scoop lump when in contact with urine (water) --- prowess in descending order:

1) Clay clumping litter
2) Swheat Scoop
3) Pet Essentials
4) Feline Pine Clumping

As you'll read in later posts, clump-ability is not the only factor in choosing cat litter. Hence, despite ranking first in this comparison, clay litter is not the final choice for my cats.
