About Rocco & Roxie Supply Co.
Rocco & Roxie Supply Co. was founded in 2013 in Utah by brothers Morgan Magleby and Matson Magleby, who named the company after their own pets, Rocco the Labradoodle and Roxie the tabby cat. The brand launched as an e-commerce-only business and grew quickly around a single breakout product, its Professional Strength Stain & Odor Eliminator, which became the top seller in Amazon's stain and odor category and was ranked among Amazon's top ten best-selling pet products for seven consecutive years. That early success carried the company into its first brick-and-mortar retail partnership with PetSmart, and in January 2023 Rocco & Roxie was acquired by PetIQ.
The catalog has since grown well beyond the original stain and odor line into treats, supplements, and grooming products for both dogs and cats. The cat-specific range includes calming chews built around melatonin, ashwagandha, and GABA, along with hairball relief chews and litter box odor control that carry the same bio-enzymatic approach as the flagship stain remover. In our own testing, the calming chew formula earned a place among our top picks for cats that need a stronger option than a plain L-theanine chew.

Rocco & Roxie Supply Co. products we rated highly
Rocco & Roxie Cat Calming Treats with Melatonin & Ashwagandha, Chicken Chews
In our cat calming treats reviews, this is one of our top picks: it stacks melatonin, ashwagandha, and GABA, which makes it the strongest-leaning formula we tested for a cat that has shown no response to a plain L-theanine chew. The multi-texture chews stood out for palatability, the usual failure point for calming treats, and a 4.2-star average across more than two thousand ratings puts it among the better-rated products we tested in the category.
