View on PurrifyWhat the maker says it is for
Rocco & Roxie lists this item as a bio-enzymatic surface spray for stains and odor. Its page does not describe use on an occupied litter box, and this page does not suggest it. The maker's directions and its FAQ differ on application timing, so this page gives none.
[1]Stain remover versus in-litter additive
The names sit close together, which is where mistakes start. One product is applied to a stain. The other is granules you mix into the box. Rocco & Roxie sells both, and only the corncob product comes with litter directions: a clean box, 2 to 3 tablespoons mixed in, and a few sprinkles after scooping. Treat them as two separate purchases, and do not assume one can be combined with the other.
[1][2]What to check before using it near a litter box
Read the front label first. The names are close.
[1][2][5]- Which bottle: stain and odor eliminator, or litter box odor eliminator.
- Fragrance: the spray panel lists it and the litter product's blend is essential-oil based. Cornell's feline health center says most cats prefer unscented, finer-textured litter, in a page updated January 2015 that is general guidance and not a verdict on any scented product.
Other ways to handle box odor
For odor inside the litter, three products are built for the job, and the picks below go by format and stated use. Rocco & Roxie's own litter product suits readers who like corncob granules and a stated starting amount. Fresh Step's scent crystals suit readers who want a crystal add-in that releases fragrance. Purrify is the one we would pair with your chosen litter: fragrance-free activated carbon, with the 120g bag as the usual start for most homes.
Routine counts too: Cornell's quick tips advise one more box than cats and daily removal of clumps and feces.
