- Entry
PrettyLitter Original is a non-clumping cat litter made of silica gel crystals, sold by PrettyLitter, Inc. of Los Angeles. The site footer names Mars Incorporated and its affiliates alongside the company. The brand describes the silica as amorphous and says the litter contains no crystalline silica. The brand says the crystals absorb urine and odor and trap them inside as the water evaporates. It comes in 6 lb bags in Unscented, Calm Aloe and Lotus Flower.
Color is the reason to buy it. PrettyLitter sells it as a health monitoring litter, and the crystals carry indicators whose chemicals the brand does not name. In its key, yellow to olive green is the typical range, blue may point to alkaline urine and orange to acidic urine, and red is blood made visible by the white crystals. The health section of its FAQ groups the colors another way, with yellow to orange as acidic and dark green or blue as alkaline, so yellow is typical on the color chart and product page but acidic there. The brand says the colors cannot identify a medical condition and points owners to a veterinarian when an unusual color persists. Where cats share a box, it suggests a second box to see which cat a color comes from. The pH at which each color appears is not published, and neither is any accuracy figure.
The routine is simple. PrettyLitter calls for 2 inches of depth, at least 3 inches for larger or older cats, with solids scooped and the litter stirred daily and the whole box refilled monthly. Its two pages disagree on the box a bag is sized for: 16 by 12 inches in the FAQ, 15 by 11 inches on the odor guarantee page. Used litter goes in the trash, never the toilet or compost. The brand says the litter has no shelf life, and that humidity, from steam for example, can interact with the crystals.
Two brand figures are worth knowing. PrettyLitter says the litter is up to 80% lighter than clumping clay, and that it lasts up to 2x longer, a claim its footnote bases on volume, with silica at 2 inches deep against clay at 3 inches.
Where it gives ground. The pricing is built around a subscription: the $24 monthly price renews every 4 weeks, not by calendar month, and a one-time bag costs $27.99. The 30-Day Risk-Free Guarantee covers first-time US customers once per household, and the refund policy excludes incorrect use and a cat that does not take to a new litter. The year founded, the country of manufacture and the test reports behind the brand's dust and odor statements are not published.
