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

PetSafe is the best-performing kitten litter box brand in July 2026, moving 40,000 units across 2 ASINs for 30.8% of Top 10 volume. Fresh Step follows with 20,000 units (15.4%), ahead of Petmate on 20,000 units (15.4%).

With 8 brands splitting the Top 10 and 61.5% 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 $4.99 to $49.24, 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: B0G52865FN booked 7K units at $16.99, with ▲ 40.0% MoM change. On the growth side, B0G1Y6ZRHK leads positive momentum with ▲ 900.0% MoM growth on 1K units, with B0H2XZJ1FR close behind at ▲ 233.3% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
