Summary
A plant-based gel that continuously neutralizes pet odors for up to 60 days without spraying or any effort. EPA Safer Choice-certified with no harsh chemicals — just set it near the litter box and let it work.

- Pairs directly with litter to neutralize odors at the source
- Mild, minty scent that doesn't overwhelm like typical scented products

Cons
- Initial scent can be overpowering when first opened
- Large rooms or multi-cat setups may need multiple jars

- Requires repurchasing regularly as an additive
Our take
For litter box areas where you can't use a spray every day, this gel is the set-and-forget solution. Plant-based, long-lasting, and tested by both The Spruce and Good Housekeeping — it's the passive deodorizer that actually works on pet odors.
This is the rare litter deodorizer that a professional pet sitter with a strong nose actually recommends — and she's tried everything. The fact that it smells 'low key pleasant' rather than overwhelming is a huge differentiator from most scented products.
