Trending Cat Flea Treatment Products — Growth Leaders & New Top 10 Entrants
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: B0002J1F7G booked 10K units at $74.98, with ▲ 0.0% MoM change. On the growth side, B00KOCCMRI leads positive momentum with ▲ 66.7% MoM growth on 1K units, with B07R9GX4XR close behind at ▲ 60.0% MoM on 8K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
