Where these numbers come from
The 7 products ranked here carry 72,565 reviews at Target. We read the newest reviews of each product (up to a thousand per listing), kept the ones that talk about odor, and counted up to 40 per product, posted between Mar 2018 and Oct 2026.
A review counts only when the reviewer used the product themselves. We drop reviews written in exchange for a free product or a sweepstakes entry (1 on this page), and products that are no longer sold.
Target also shows reviews first posted on brands' own websites. We show them on product cards but never count them, because brand-site reviews run more positive than store reviews of the same products.
Because we searched for the problem, people who had it are overrepresented. Compare products with each other rather than reading a share as your own odds.
We count what pet owners report. Nothing here is veterinary advice: if a pet stops eating, gets sick or keeps scratching, ask your vet.
Amazon buttons appear only on products that most pet owners here say fix the problem (at least 60%, with enough reviews to trust it). Everything else gets no buy link.
An AI model labels each review against a fixed list of points, and we spot-check the labels before publishing. We publish counts, never the reviews themselves.
