Fur-midable Growth: Pets Dominate Amazon

63% Drop in Amazon Out-of-Stock Losses

Yes, pet brands cut their out-of-stock losses by 63% in a single quarter.

CommerceIQ data shows pet category sellers on Amazon grew revenue 20% year-over-year in Q2 2026 > the only tracked category to reduce out-of-stock losses during a quarter that included Prime Day.

Now the question is, how did they pull that off without discounting?

Supply chain execution. On-hand inventory rose 11%, out-of-stock rates fell to just 1% (the best in-stock rate of any category tracked), and purchase order fill rates climbed to 89%.

Interesting thing to watch out for: ad spend jumped 28% and ROAS improved to 4.4x, but conversion rate actually dropped 6 points to 52%. So the growth story is inventory discipline, not just throwing more ad dollars at the funnel.

30% gross margin: pet trailed only office products for the strongest growth-to-margin balance in CommerceIQ's entire dataset.

However, unlike a single-company announcement, this is aggregated, anonymized data across the whole pet category - CommerceIQ didn't break out which specific brands or SKUs drove the numbers.
