Frequently Asked Questions
Our non-clumping litter bags weigh 6 lbs, while our clumping litter bags weigh 10 lbs. Compared with traditional clay litter, PrettyLitter's lightweight formula can make it easier to carry, handle, and dispose of.
In a household with a single cat, a 6lb bag of litter lasts about a month before needing to be replaced. However, there are some factors that can affect consumption such as the size of the cat's litter box and how often it gets scooped and replaced. Our silica gel crystals are extremely absorbent, so you'll likely need less of it to do the same job.
Litter boxes using PrettyLitter should have two inches of depth to them, so the correct amount of kitty litter will vary on the size of the litter box. With PrettyLitter's absorbent silica-gel crystal formula, one fill should last an entire month for one medium-sized cat.
Yes. You can buy PrettyLitter as a one-time purchase. However, a subscription offers added convenience, automatic delivery, and savings. You can also cancel anytime.
PrettyLitter changes color based on your cat’s urine pH. Yellow/olive green is typical, while blue may indicate alkaline urine, orange indicates acidic urine, and red indicates visible blood. Color changes can help monitor your cat’s health but cannot diagnose medical conditions. Contact your veterinarian if you notice unusual colors.
Yes. PrettyLitter is made with amorphous silica gel — a non-toxic, pet-safe material. It's important to note that not all silica is the same: amorphous silica (the kind used in PrettyLitter) is safe, while crystalline silica (found in some clay litters) can be harmful when inhaled over time. And those "Do not eat" labels you see on silica packets? They signal a choking hazard, not toxicity.
Safety is backed by rigorous third-party testing for both respiratory and digestive safety, plus ongoing toxicologist review of all materials.

PrettyLitter offers both Original Non-Clumping and Clumping formulas. Original PrettyLitter absorbs urine without forming clumps, while PrettyLitter Clumping forms scoopable clumps for easier cleanup.
PrettyLitter is made with super-absorbent silica gel crystals designed to absorb urine and help control odor. The litter also contains a health-monitoring formula that can help indicate changes in urine pH and visible blood.
Non-clumping PrettyLitter is compatible with most self-cleaning, automated litter boxes. Clumping PrettyLitter is not recommended for automated litter boxes.
Many customers love using our litter in the Litter Robot 3 and earlier generations of the Litter Robot, along with other manufacturer’s models. PrettyLitter is not ideal for the Litter Robot 4, because the machine’s sensors do not detect our light-colored litter.
If you have questions about a specific make and model, we recommend reaching out to the manufacturer to ensure compatibility.

How PrettyLitter Works
PrettyLitter changes color to tell you when your cat has a potential health issue, so you can get them help before it becomes an urgent medical situation. Our silica litter (crystal cat litter) could save you big money on expensive vet bills, not to mention it could save your cat's life.
Typical
Dark yellow / olive green indicates urine within a typical, healthy range.
Orange
Acidity outside the average range, which may be a sign of metabolic acidosis or kidney tubular acidosis. Calcium oxalate crystals can be more likely to form in acidic urine.
Blue / Dark Green
Alkalinity outside of the average range may be present if your cat has certain types of urinary tract infections (UTI). Highly alkaline urine can increase the risk of struvite crystal/stone formation.
Red
Visible presence of blood, which may indicate Feline Lower Urinary Tract Disorder (FLUTD), bladder stones/crystals, kidney stones, bladder inflammation, certain types of kidney disease and clotting disorders.
You can buy a single bag of litter as a one-time purchase if you want to try it, or set up a subscription so litter arrives automatically when you need it. Our subscriptions are flexible—you can pause or cancel anytime. This not only gives you peace of mind that your cat’s litter box is always stocked, but also helps you keep track of their health consistently without worrying about running out or missing important changes.
