Litter Box Liners Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Purina Tidy Cats is the best-performing litter box liners brand in July 2026, moving 20,000 units across 1 ASIN for 23.8% of Top 10 volume. Litter Genie follows with 20,000 units (23.8%), ahead of JONNY CAT on 13,000 units (15.5%).

With 8 brands splitting the Top 10 and 63.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $6.56 to $27.40, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B07K8Y256B booked 3K units at $21.59, with ▲ 0.0% MoM change. On the growth side, B0GKWV6V9W leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B0FXGHY1SG close behind at ▲ 100.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
