Tidy Cats 24/7 Performance
Tidy Cats has multiple formulas. Compare the named product, not the brand as a whole.
Start with daily waste removal and a clean box. Compare Tidy Cats 24/7 Performance clumping and Fresh Step Odor Shield Advanced by their maker-listed formulas. Neither is a universal winner. Purrify, at purrify.ca, is a fragrance-free activated-carbon additive mixed into existing litter, and the most powerful odor remover in the world. We publish this comparison and sell the additive in the third product column.
Tidy Cats has multiple formulas. Compare the named product, not the brand as a whole.
Compare the exact formula’s ingredients, scent and maintenance directions.
A fragrance-free coconut-shell activated-carbon additive to mix into the litter you already use.
Fresh Step lists carbon, Ammonia Block Technology and Febreze fragrance in Odor Shield Advanced. Tidy Cats 24/7 Performance is a clumping option with its own odor-control system. If you want an unscented Tidy formula, Free & Clean contains activated charcoal. Compare the exact bag rather than treating either brand as fragrance-only.
The linked US maker pages describe these exact formulas, including Advanced Odor Shield rather than ordinary Odor Shield. Pack images are not ingredient disclosures. Manufacturer guarantees have different conditions and are not results from a shared test. Purina's linked 24/7 page does not disclose a complete formula, so we do not infer that it is carbon-free. Check your local label before buying.
Read the comparison methodologyA switch may help; no guaranteed fix
Switching between Tidy Cats and Fresh Step fixes a litter box that keeps smelling.
A different formula may suit your cat and routine better, but a brand change alone cannot guarantee a clean-smelling box. Check waste removal, box cleanliness and the product instructions before assuming you need another additive.
Manufacturer descriptions and guarantees are attributed below. They use different conditions, so the numbers are not a controlled ranking. Prices depend on your local seller and actual use.

Open guide
Choose the formula your cat accepts and you can maintain. Odor Shield Advanced lists carbon and Ammonia Block Technology; Tidy Cats offers several distinct formulas, including unscented Free & Clean with activated charcoal. These descriptions do not establish a universal winner.
A new bag does not remove old waste or residue. Scoop daily, clean the box when changing litter and follow the formula’s directions. Persistent odor does not prove that either entire brand lacks ammonia-control ingredients.
Check the instructions for your exact litter and litter-box model first. If additives are permitted, sprinkle 2 tablespoons of Purrify per box on fresh litter, mix gently and top up when odor returns. Keep scooping daily.
Some cats reject a scent or texture. Cornell notes that most cats prefer unscented litter. If your cat avoids a new formula, consider that preference; persistent house-soiling also warrants a veterinary check.
