Litter Box Supplies
Waste bags and trays for self-cleaning boxes, standard liners, disposal pails and their refills, compared on what they fit and how long the maker says they last.
Supplies are where a litter setup's real cost lives. Self-cleaning boxes take their own drawer bags or trays; disposal pails take their own film refills. Third-party refills can cut costs, but the fit is only as good as the seller's compatibility statement.
We list what each product says it fits and how long one unit lasts for one cat, so you can match refills to your box and work out the monthly cost.
What decides it
Fit
Match the exact model and generation; a bag for one box can be the wrong size for its successor.
Life per unit
Stated life is for one cat; more cats use refills proportionally faster.
Official or third-party
Official refills fit exactly; third-party refills cost less but rely on the seller's fit claim.
Monthly cost
Compare cost per month, not per pack, with the calculator.
