Frequently Asked Questions
Our litter bags weigh 6 pounds per bag. PrettyLitter is up to 80% lighter than traditional clay litter. Gone are the days of taking huge trash bags of heavy pet waste to the garbage. You can now handle and dispose of your cat waste with less effort.
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 without a subscription! However, subscribing is usually the better value compared to a one-time purchase because it saves you money and saves you the hassle of remembering to reorder. With a subscription, your bag of litter ships automatically on a schedule that works for you, and you can cancel anytime. If you’re looking for an easy way to buy cat litter online and want to save more in the long run, our subscription is the way to go.
PrettyLitter reacts to the pH of your cat's urine. When urine comes in contact with the litter, it can turn orange, green or blue. If there is noticeable blood present in the urine you will see red on the white litter.
When the litter is olive green to yellow, your cat's urine is within the typical range. Want to test this color? Tap water will have a similar pH and show green to yellow.
The litter turns blue when urine is more alkaline than normal, which may indicate a urinary tract infection, for example. Want to test your litter? Ammonia will have a similar pH and show blue.
The litter turns orange when urine is more acidic than the normal range. This may mean bladder crystals or stones. Want to test this color? Vinegar will have a similar pH and show orange.
Because our litter is white, blood in urine appears red and is easy to spot. We advise against mixing PrettyLitter with any other litter because it can affect the visibility of the color change and its performance.
Our Veterinarian in Chief says: PrettyLitter will help you monitor your cat’s health in detecting abnormalities in your cat’s urine by testing acidity and alkalinity levels and the visible presence of blood. PrettyLitter cannot detect every feline health issue or prevent or diagnose diseases. A diagnosis can only come from a licensed veterinarian.

Yes, PrettyLitter is safe for cats and families. Here’s the science behind our safety:
- Amorphous vs. Crystalline Silica: PrettyLitter is made of amorphous silica gel, which is fundamentally different from crystalline silica. Crystalline silica - found in some clay litters - can pose health risks when inhaled over long periods. Amorphous silica is non-toxic and pet-safe.
- Widely used in consumer products: The same amorphous silica in PrettyLitter has been used in topical medicines and cosmetics for decades. You may recognize it from food packets, toothpaste, and other household products.
- Backed by science: PrettyLitter was created with cat healthcare at its core, developed by veterinarians specifically for feline health monitoring.
- No Crystalline Silica: PrettyLitter contains no crystalline silica - only the safe amorphous form.
- Household Friendly: Safe for families with children and multiple pets. The amorphous silica gel is inert and non-toxic.

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
Orange may indicate a pH consistent with metabolic acidosis or kidney tubular acidosis. Calcium oxalate crystals can be more likely to form in acidic urine.
Blue / Dark Green
Blue may indicate a pH consistent with urinary infections or higher stone risk. Highly alkaline urine can increase the risk for struvite crystal/stone formation.
Red
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. In rarer cases it can also mean bladder cancer or an internal injury.
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.
