Our take
If odor is your #1 concern — especially with cats in a living space — Clump & Seal Platinum is the one. The baking soda formula genuinely neutralizes ammonia smell in a way plain clay can't match.
If you're budget-conscious and don't want to sacrifice basic performance, Special Kitty is the honest answer. It's not perfect, but at 48¢/lb it's hard to argue with for everyday use.
