Listed ingredients: cold-pressed orange peel oil, plant-derived surfactants, filtered water, sodium benzoate and citric acid. [1]

The maker's directions say to add it straight to any type of litter. Sodium bicarbonate is the named deodorizer. [2][3]

View on PurrifyWhat the maker says it is for
Angry Orange's page sells a Pet Odor Eliminator Concentrate with a citrus scent. It does not present the product as a litter additive, and this page does not suggest using it in a litter box. Dilution amounts and timing are left out on purpose, so follow the maker's own directions.
[1]Cleaner versus in-litter additive
A surface product is applied to a spot or an area. A litter additive is mixed into the litter itself. Angry Orange is sold as a concentrate to be diluted, which puts it in the first group by format. How you apply it is for the maker's directions to say. A shopper who assumes any pet odor product works inside litter can buy the wrong thing, and nothing on this page suggests pairing a cleaner concentrate with a litter additive in one box.
[1]What to check before using it near a litter box
Two checks come first.
[1][6]- The maker's directions and ingredient list, read in full. This page does not recommend applying the concentrate in an occupied litter box.
- The citrus scent. Cornell's feline health center says most cats prefer unscented, finer-textured litter. That page, updated in January 2015, covers litter, not sprays, and is not a verdict on any scented product.
Other ways to handle box odor
For odor inside the litter, pick by format and stated use. Going by the maker pages, Arm & Hammer's powder suits readers who want a product the maker says goes into any type of litter, and Rocco & Roxie's corncob granules suit readers who want a stated starting amount of 2 to 3 tablespoons. Purrify is our preferred pairing with whatever litter you choose. It is fragrance-free activated carbon sold in bags, and the 120g bag is where we start most homes.
