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

Greenies is the best-performing cat grass treats brand in July 2026, moving 32,000 units across 2 ASINs for 34.0% of Top 10 volume. Temptations follows with 20,000 units (21.3%), ahead of Pet Honesty on 20,000 units (21.3%).

With 9 brands splitting the Top 10 and 76.6% 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 $7.72 to $15.99, 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. On the growth side, B0GKPHP8VM leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B0B9QSQP5Q close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
