http://crystalxfreshkitty.com/We have managed, through a proprietary process, to capture and preserve the unique energy-release properties that we have identified in the several forms of silica that we use. These natural energy-release properties safely condition the high protein foods cats consume, and can metabolically break down the urea in your cat’s system – and the smell of urine – before your cat uses the litter box.
This page shows how you're supposed to use it:

I have no clue what the actual science of this is--or if it works for bladder crystals, etc. It sounds a bit bizarre to me, especially the bit about the canned cat food, but hey. You never know! The part about breaking down urea is what caught my eye after reading a lot of posts about bladder crystals.
