Overview
['This 5 lb bag of Ultra Pearls is built from silica gel crystals, marketed as 99.9% dust free, low tracking, and fragrance free. Ultra Pet also positions it as soft on paws, a detail aimed at cats that seem bothered by coarser clay or pellet textures.', 'As a crystal litter, it works on the same absorb-rather-than-clump principle as other silica products, so day-to-day maintenance means periodic full changes instead of daily clump scooping. The small 5 lb size makes it easier to try before committing to a larger bag.', "At $16.99 for 5 lb, it's priced in the middle of the pack for crystal litters, and with 2,500 reviews averaging 4.0 stars, it has a decent track record, though it trails some of the higher-rated clumping and crystal alternatives in this lineup."]

Performance notes
The 99.9% dust free and low tracking claims point to a finer, more controlled crystal size than some bulkier pellet or clay formulas, which can matter for households sensitive to airborne litter dust. Being fragrance free also sets it apart from the many Febreze-scented options in this category.
What buyers say
With 2,500 reviews and a 4.0 star average, this product sits below the other litters reviewed here, though it's still a majority-positive rating, and around 700 buyers per month keep it moving steadily.
No, Ultra Pearls is formulated fragrance free, which is one of its main selling points for cats sensitive to scented litter.
How dusty is this litter?

Why is the rating lower than other litters in this lineup?
At 4.0 stars across 2,500 reviews, it's still majority positive, but it trails some of the higher-rated clumping and crystal alternatives, so it's worth weighing against options with stronger review averages.
