Overview
["This is PetSafe's ScoopFree crystal litter, built specifically to work with PetSafe's ScoopFree line of self-cleaning litter boxes, though it can be used in any litter box. It is a silica gel pellet formula with a Fresh scent, sold in an 8 lb bag.", "Crystal litter like this absorbs urine into the silica pellets and helps dry out solid waste, which is the mechanism ScoopFree's automatic rake system is designed around. The Fresh scent adds an extra layer of odor control on top of the silica's natural absorbency.", 'At $22.99 for 8 lbs, it is priced for what is a smaller bag size than the bulk clay boxes in this category, but it has built strong credibility with more than 2,400 reviews at a 4.6 star average and about 9,000 bags bought in the past month, ranking #35 in Cat Litter.']

Performance notes
This crystal litter is designed around PetSafe's ScoopFree automatic litter box system, where the silica pellets absorb urine and help dry solid waste for the rake mechanism to manage, though it works in standard litter boxes as well. The Fresh scent layers on top of the silica's own odor-absorbing properties.
What buyers say
More than 2,400 reviews at a 4.6 star average, along with about 9,000 bags bought in the past month, make this one of the best-performing and most popular products in this litter lineup.
No, it works in any standard litter box, though it is specifically formulated to pair with PetSafe's ScoopFree self-cleaning litter box system.
Is it scented?
Yes, it carries a Fresh scent on top of its silica crystal formula's natural odor absorption.
How long does an 8 lb bag typically last?
That depends on how many cats you have and how often the box is used, but crystal litter is generally used more sparingly than clumping clay since it is changed on a schedule rather than scooped daily.
