No vet guide we read names one least toxic cat litter; they tell you to check three things: how much dust it makes, whether it has added scent, and what your cat may swallow while grooming.
Whichever litter you pick, Purrify goes in it and holds the odor there, so you do not need a scented litter to cover the smell.
Choosing a natural litter? See Purrify, the fragrance-free additive for natural litters.
| Litter | Dust | Paws and swallowing | Scent |
|---|---|---|---|
| Clay | Produces dust that can be irritating for both cats and people with respiratory issues. | Some cats may ingest small amounts while grooming, which can lead to digestive blockages. | - |
| Silica crystals | - | Can be harsh on sensitive paws. | - |
| Pine, corn or recycled paper | Low in dust. | - | - |
A dash means the guides we read say nothing about it. Scent is covered below, for every litter at once.
Humane World for Animals says scented litters mask odors for humans but can overwhelm cats, and advises avoiding strong scents and air fresheners near the box. Cornell Feline Health Center advises a non-scented litter. Our guide to fragrance-free litter deodorizers covers the same idea for the deodorizer you add.
VCA tells owners to consider health concerns of both cat and person, such as asthma or allergies. If either applies, ask your vet before you switch. For a closer look at low dust options, see our dust-free litter guide.
Purrify is fragrance-free activated carbon, so it adds no scent for your cat to object to. It works with every litter, clumping included, which lets you choose the litter for your cat and your household and handle the odor separately.
None of the guides we read ranks litters by health. The table above shows what VCA says about dust, paws and swallowing, and the scent section shows what Humane World and Cornell say. With asthma or allergies in the home, ask your vet first.
None of the guides we read labels one litter as non-toxic. They compare litters on dust, scent and what a cat may swallow, so start with the table above and your vet.
Purrify is 100% steam treated coconut shells you mix into the litter you already use. It traps odors more effectively than anything else on earth.
Sprinkle 2 tablespoons of Purrify granules per litter box on fresh litter and mix gently. Top up whenever the box starts to smell again.
