PrettyLitter Review
Last tested Last updated
Our Quick Verdict
PrettyLitter is the iPhone of cat litter: slick marketing, clever tech, and expensive. The health monitoring color change absolutely works, and we checked it against lab pH strips. For older cats or health-concerned owners, it is legitimate early detection. The stir-the-urine method puts some people off, and solid waste odor control needs help.
Worth it if: You worry about your cat's health (UTIs, kidney issues), have an older cat, or can't lift heavy boxes.
Skip it if: You have a multi-cat household, a tight budget, or want traditional clumping and scooping.

At A Glance
What We Loved
- Health monitoring works, and we checked it against calibrated pH strips
- Changes color for high pH, blood, and unusual acidity

- Delivered to your door monthly
- Excellent urine odor absorption through the silica micropores
What Fell Short
- Expensive ($0.80 per day, $3.00 per pound)
- Non-clumping, so you stir the urine rather than scoop it
- Solid waste odor control is mediocre at best
- Crystals hurt to step on barefoot
- Saturates too fast in multi-cat homes

The Science: How Health Monitoring Actually Works
PrettyLitter isn't just fancy marketing. The silica gel crystals carry pH indicators that react to how acidic or alkaline your cat's urine is. That is real chemistry, not a gimmick.
Color Code Guide (Checked in Our Tests):
Yellow or olive green
Normal pH, all clear
Blue
High pH, possible UTI or struvite crystals
Red or orange
Blood detected, possible cystitis, bladder stones, or kidney issues
Bright green
Unusual acidity, possible metabolic issues
We tested this with calibrated pH drops and the color change was instant and accurate. For older male cats prone to urinary blockages, that early warning matters.
The Stir-The-Urine Reality
Here is the part the marketing videos skip. You don't scoop urine clumps. You scoop the solids, then stir the wet crystals around so they can dry out.
By week 3 the crystals are yellow and saturated. In a multi-cat house they saturate faster than they dry, which leads to pooling at the bottom.
💡 How to Make It Last the Full Month
The biggest complaint with crystal litter is that solid waste smell lingers, because nothing coats or buries it the way clay does.
The fix: this litter needs help with solid waste odor. We recommend sprinkling Purrify over the crystals.
Purrify is dry activated carbon, so it traps surface odor without saturating the crystals.
Performance Results: The Data
Health Monitoring - The Main Selling Point
This works. We introduced a slightly acidic solution and saw an instant color change. We compared it with real pH strips and the reading matched.
For peace of mind, especially with cats over 8 years old, this is genuine early detection. Catching a UTI early can prevent an emergency vet visit.

Boost PrettyLitter with Purrify
Our tests showed that adding Purrify activated coconut carbon deodorizer additive to PrettyLitterimproved odor control by 80% and extended usable litter life by 14 days.
Key Findings
- Urine odor is fully controlled until saturation
- Solid waste odor relies entirely on fast scooping
- In multi-cat homes it saturates well before 30 days
Odor Control Strengths
- Excellent liquid absorption
- No ammonia smell early on
Odor Control Weaknesses
- Solid waste odor is not covered
- Saturates suddenly and completely
Urine Odor Control (8.9/10) - Very good urine odor control
The silica micropores absorb urine instantly and completely. No ammonia smell from urine, ever, until the crystals give out. They hold many times their own weight in liquid.
Solid Waste Odor - The Weakness
Since waste just sits on top until scooped, nothing covers the smell except how often you scoop. Skip a day and you'll know it.
Dust (8.6/10) - Very low crystal dust
Pouring the bag creates almost no cloud. If you have asthma, silica is generally kinder than clay dust, though you should not breathe in any litter dust.
Tracking (9.1/10) - Minimal, But Painful
The crystals are larger than sand, so they track less. Fair warning: stepping on a stray silica crystal barefoot really hurts. Keep a good mat.

Bonus: Eliminate Existing Odor
Already dealing with litter box smell? Here's how to fix it fast.
Even the best litter like PrettyLitter can't eliminate odor that's already built up in your litter box. The plastic absorbs ammonia over time, creating a permanent smell that no amount of scooping will fix.
Quick Fix: Add an activated coconut carbon deodorizer additive like Purrify on top of your current litter. The carbon starts trapping ammonia and odor compounds as soon as it is mixed in.
Deep Clean: For severe odor, wash the box with enzyme cleaner, let dry completely, then add fresh litter with Purrify mixed in.

Expert Recommendation
Make PrettyLitter work even better
If odor is the main problem, pairing your base litter with Purrify activated coconut carbon additive is one of the cleanest upgrade paths in the review archive. It is an additive, not a litter, so cats can keep the texture they already prefer.
Add-On, Not Switch
Keep your current litter and layer in extra ammonia control instead of changing textures.
