Boxiecat litter is a clumping clay built around one idea: clumps should form at the top of the litter, not sink and stick to the bottom. The brand also sells a non-clumping crystal formula that works a completely different way.
Pick Premium Unscented for an everyday clay with no fragrance. Pick Gently Scented if you want a light scent. Pick Extra Strength if you want Boxiecat’s multi-cat, probiotic clay formula. Pick Probiotic Crystal if you’d rather not deal with clumps at all.
Boxiecat now also features newer BoxiePro formulas, including Deep Clean, Glo Attract, Bot and Lightweight. This review focuses on the Boxiecat formulas linked here.
How Boxiecat Litter Works
Boxiecat says its clay forms flat clumps on top of the litter bed, to keep them from sticking to the sides or bottom of the box. Many reviewers say the clumps lift out cleanly with little scraping. Several say they change the whole box less often than with their old clay.
The Probiotic Crystal is a non-clumping silica crystal litter. Urine is absorbed into the crystals, while solid waste is scooped separately.
Boxiecat Formulas Compared
| Formula | Type | Scent | Best For |
|---|---|---|---|
| Premium Unscented | Clumping clay | Unscented | Everyday use, one or two cats |
| Premium Gently Scented | Clumping clay | Light, moisture-activated | Owners who want a faint fragrance |
| Extra Strength | Clumping clay with probiotics | Sold as unscented | Multi-cat homes |
| Probiotic Crystal | Non-clumping silica | Check listing | Owners who’d rather not scoop clumps |
Boxie Premium Unscented Clumping Cat Litter
Why It Stands Out
It’s the original Boxiecat formula. In one reviewer’s detailed six-brand comparison, it tied for best. Many reviewers report low dust and less tracking than finer clumping litters.
Possible Downsides
Extra Strength is the formula Boxiecat specifically positions for multi-cat and higher-odor use, so busy multi-cat boxes may suit that one better.
Best For
One or two cats, and owners who want a clumping clay with no fragrance.
Boxie Premium Gently Scented Clumping Cat Litter
Why It Stands Out
It’s the Premium clay with scent added. Boxiecat describes the fragrance as light and moisture-activated, and one reviewer says it’s barely noticeable.
Possible Downsides
It’s still scented. If your cat has avoided scented litter before, choose Unscented.
Best For
Owners who want a faint fragrance and whose cats accept scented litter.
Boxie Extra Strength Clumping Cat Litter
Why It Stands Out
Boxiecat sells it for multi-cat homes and “extra stinky” boxes. It uses the same flat-top clumping idea as Premium, plus a probiotic blend Boxiecat says helps stop odors. Boxiecat sells it as unscented. One reviewer in an eight-cat home says she changes the whole box far less often than before. It comes in a 16 lb bag and a 28 lb bag.
Possible Downsides
It’s still a clumping clay, so it uses the same basic scoop-and-top-up routine as Boxiecat’s other clay formulas.
Best For
Multi-cat homes that want a probiotic clay.
Boxie Probiotic Crystal Cat Litter
Why It Stands Out
It’s a non-clumping silica crystal with what Boxiecat calls MicroDry probiotic technology, aimed at odor. Several reviewers who’ve tried many crystal litters rate it highly, and many say it’s low in dust. Boxiecat says the crystals change appearance as they’re used, which can help show how much of the litter is saturated.
Possible Downsides
It doesn’t clump, so the routine is different from the clay formulas: scoop solids and stir the remaining crystals according to the bag directions.
Best For
Owners who want to skip clumps, and cats that accept crystal.
Frequently Asked Questions
Is Boxiecat litter low dust?

Does Boxiecat work in automatic litter boxes?
Check your machine maker’s litter guidance first. Our best cat litter for automatic litter boxes guide covers what each machine needs.
