Pretty Litter

PrettyLitter Health Monitoring Cat Litter (Unscented, Non Clumping) | Lightweight & Low Tracking, Color Changing Silica Gel Crystals, Advanced Odor Control — 6 Lbs, Pack of 1 (Up to 1 Month Supply)

Free Shipping

Why We Love It

PICK OF THE LITTER: Low-maintenance litter shouldn't be a luxury. Made to be low tracking, low dust, and up to 80% lighter than traditional clumping clay litter, our absorbent silica gel formula means no weekly refills or pee clumps just scoop the poop.
MONITORS HEALTH: By changing colors based on urinary PH and the presence of blood, this litter helps indicate certain types of potential issues like feline UTIs, kidney disease, bladder crystals & metabolic acidosis early for peace of mind with every pee.
ADVANCED ODOR CONTROL: Silica gel crystals absorb moisture through millions of micropores, trapping urine inside (not just clumping around it) and dehydrating feces to neutralize odors before it's time to scoop.
SAFE & EASY: Veterinarian developed and free from crystalline silica & propylene glycol, PrettyLitter is safe for both cats and kittens. Each 6-pound bag lasts up to one month per cat, simplifying litter box care while saving space in your closet.
LITTER BOX COMPATIBILITY: Whether you're a multi-kitty or solo cat household, we cater to every feline family, which is why our scented and unscented formulas work with regular litter boxes, automatic self-cleaning litter boxes, and more.
