A strong smell from the litter box is rarely just a litter problem. When food passes through without being properly absorbed, the result shows up in the box, and no amount of scooping fully fixes it.
The five products below attack the smell from different directions: digestive kibbles, a probiotic chew, a sensitive-stomach formula, and one deodorizer that works on the box rather than the bowl. The table up front sorts them by mechanism, so you can see at a glance which approach each one takes.

Conclusion
Smell from the litter box usually traces back to digestion, and digestion is shaped by what goes into the bowl. The products here work from different angles: four of them are foods or supplements described as supporting digestion, and one is a deodorizer that treats the box itself.
Pick the angle that matches your situation, and keep the vet boundary in view: sudden or lasting changes in stool, appetite, or weight are questions for the vet, not reasons to keep swapping foods.
