Arm & Hammer HardBall is the strongest all-around pick in this comparison for fast hard clumping on a mid-range budget.
Zero-silica, zero-clay pine pellets with naturally low dust, but they require a sifting setup and a cat that accepts pellets.
Fast-forming hard clumps with baking soda odor help, making it a strong mid-range clay pick if you can tolerate moderate dust.
HardBall clumps fast and hard. Feline Pine does not clump at all, costs less per day, and leaves the room clear when you pour it. Sifting tray required, and not every cat agrees to pellets.
This comparison page is maintained by the ReviewCatLitter editorial team and grounded in the same scoring framework used across the published review catalog.
Choose between them on texture, clumping, dust and price. Then, if the room still tells you where the box is, Purrify is activated carbon you mix into whichever bag you chose. It is what we use in our own homes.

Neither run recorded granules outside the box, ammonia after one day and ammonia after three days, so those rows are left out rather than filled in from a similar bag. The full test data shows every reading we have.
Primary tradeoff: Arm & Hammer HardBall's weakest area here is dust control.
Strongest odor control in this set with baking soda support.
Clumping is a real edge: hard and fast.
It still lands a stronger overall score than cheaper options because it is more balanced.

Ultra is the cleaner litter. HardBall is the cheaper way to get clumps that set fast and come out in one piece.
Two Arm & Hammer clays built for different things. Clump & Seal is about fragrance and a low bag price.
Ultra clumps and Feline Pine does not, which decides most of this. Pine pellets cost far less per day and need a sifting tray.
Pine pellets cost less per day than Clump & Seal and pour almost no dust, but they do not clump and they need a sifting tray.
HardBall is the cheaper way to get clumps that set fast and lift whole. Cat Attract only earns its price if your cat has stopped using the tray.
Neither clumps. PrettyLitter is for watching your cat's health and lifting a light bag. Feline Pine is for a sifting tray and a far cheaper month.
