Cat Diapers Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Wowflash is the best-performing cat diapers brand in July 2026, moving 10,000 units across 1 ASIN for 23.8% of Top 10 volume. Amazon Basics follows with 8,000 units (19.0%), ahead of Wet Ones on 7,000 units (16.7%).

Volume is spread across 9 brands, with the top three holding 59.5% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $4.99 to $34.99, 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: B0BTL3RS4G booked 1K units at $8.63, with ▲ 0.0% MoM change. On the growth side, B0F4JBQGK1 leads positive momentum with ▲ 100.0% MoM growth on 200 units, with B074P4NZLM close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
