Summary
Baking soda-powered odor elimination with tight, easy-to-scoop clumps. Tens of thousands of five-star Amazon reviews and consistent Reddit recommendations make this the top pick for odor-sensitive households.
Walmart's house-brand clay litter at under 50¢/lb — the cheapest clumping option that actually works. Unscented, easy-pour jug design, and multi-cat capable make it a genuine value pick.
Pros
- Baking soda formula provides superior odor absorption
- Forms tight, firm clumps that don't break apart during scooping
- Works well in automatic litter boxes
- Tens of thousands of five-star Amazon reviews and widely recommended on Reddit
- Lowest cost per pound (~48¢) of any recommended clumping litter
- Easy-pour 14-lb jug with screw-top lid — no heavy bags
- Unscented bentonite clay formula works for multi-cat households
- Recyclable jug packaging
Cons
- Scented formula — a dealbreaker for cats sensitive to fragrance
- Some tracking reported
- Higher cost at ~$1.05/lb compared to unscented alternatives
- Tracks more than premium options — expect some litter outside the box
- Clumps not quite as tight as Dr. Elsey's or Arm & Hammer
- Only available at Walmart — not sold on Amazon or Chewy
Our take
If your litter box is anywhere near living space, Clump & Seal is your answer. The baking soda formula genuinely neutralizes odor — testers reported no smell even after going unscooped for several days.
Don't let the low price fool you — Special Kitty holds its own against litters twice the cost. If budget is your primary concern and you don't mind a quick sweep around the box, this is the smart buy.
