Chewy.com has the highly-rated Dr. Elsey's Precious Cat Ultra Clumping Cat Litter in 40 lbs bag size for a low price of $10.49. The lowest price it has been lately; and still, the best deal around, considering free shipping on orders over $49, and tax-free in most states. This is by far the best cat litter out there, and currently, Chewy.com seems to have the best price. Free shipping too, which is great, considering the 40-pound bag size.

Dr. Elsey's Precious Cat Ultra Clumping Cat Litter is a unique formulation that combines the heavy non-tracking granules of Precious Cat Classic with a medium grain clay. The result is an excellent clumping litter that prevents moisture from reaching the bottom of the tray, while providing a clump that will not break down. Ultra is perfect for multi-cat families and those cat owners with sifting or mechanical litter boxes. Like Classic, it has superior odor control.
