Royal Canin Cat Food Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Hill's Science Diet is the best-performing royal canin cat food brand in July 2026, moving 31,000 units across 4 ASINs for 39.7% of Top 10 volume. Purina Pro Plan follows with 17,000 units (21.8%), ahead of Blue Buffalo on 15,000 units (19.2%).

With 5 brands splitting the Top 10 and 80.8% 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 $35.40 to $48.99, 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, B000YK7V9O leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0030N1OZE close behind at ▲ 50.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
