The 34-pound Catalyst bag provides a larger quantity of the unscented clumping softwood litter. Consider it when you already know this litter format works in your setup and have suitable storage, rather than using a large bag as the first trial.
Before you choose
Compare price per pound with the 15-pound listing, while keeping lifting and storage space in mind. Do not apply a clay-litter scoop or automatic-box assumption without checking compatibility. Refill depth and cleaning frequency should follow the litter and box instructions.

Questions about this product
Does the four-month claim apply to every household?
No. The advertised duration is an estimate for an average single-cat household. Actual use depends on the box, litter depth, cleaning routine and number of cats.
How does this bag differ from the 15-pound Catalyst option?
This is the 34-pound unscented clumping softwood option. The larger package changes how much litter you receive, not the basic wood-versus-clay distinction or the need for daily cleaning.
What is the litter material?
The litter material identified for this package is pine.
