Overview
["This 5 lb bag of silica gel crystal litter is built around a micro crystal format rather than traditional clay granules, which Ultra markets as 99.9% dust free and soft on paws. The Summer Breeze scent adds a light fragrance on top of the crystal's natural odor-absorbing properties.", 'Silica crystal litters like this one work by absorbing moisture and odor into the crystal structure rather than clumping the way clay does, so the maintenance routine looks a bit different, typically involving stirring and spot removal of solid waste rather than daily clump scooping.', "At $16.99 for 5 lbs, it's a mid-range price for a crystal litter, and with 1,417 reviews averaging 4.3 stars and about 2,000 units bought last month, it has a solid, consistent following."]

Performance notes
The micro crystal item form is made from silica gel, which absorbs liquid and odor into the crystal rather than forming a solid clump, so upkeep generally means removing solid waste and periodically checking or replacing crystals as they become saturated. The 99.9% dust free claim and soft on paws description point to a formula meant to be gentler underfoot than coarser clay litters.
What buyers say
With 1,417 reviews and a 4.3 star average, plus roughly 2,000 units bought in the past month, this is a well established, popular option within the crystal litter niche.
Does crystal litter need to be scooped daily like clumping litter?
Not in the same way. Crystal litter absorbs moisture rather than clumping, so the routine is usually removing solid waste daily and letting the crystals absorb liquid until they need a full change.
Is the Summer Breeze scent strong?
Ultra markets this as a lightly scented formula, but scent strength is subjective, so cats sensitive to fragrance or owners who prefer unscented litter may want to test a small amount first.
