crystal cat litter !!

As a pet sitter I come across lots of different cat litter some good some rubbish at the moment i am looking after 2 cats and they have this crystal cat litter and its GREAT. usually with 2 cats I do a full change every other day but this has been a week now and still not had to change it just scoop out the poo and thats it, & it doesn't smell!!!!
I read the bag this morn as I was going to change it today but still not a whiff from it and it said to change when most of the crystals are yellow, so I will probebly change it tmrw. sooooo was wondering have any of you guys used it for hedgies The girl I bought Ruffles from was using it in the litter tray, but I havn't seen it since saying that I have not looked for it but after the impressive results I have seen this week from 2 indoor cats and still no smell I thought would like to try it any ideas??

Sounds like fab stuff, I would like to know if it would be safe to use too
Do you have any links to where to buy it from? Or pics? So we can get a better idea of how it looks...
I just can't picture it!

this is what I have just found out about it:-
Silica gel litter
often referred to as "crystal litter", is a porous granular form of sodium silicate, has the highest absorbency of any litter, and has excellent moisture control and complete odor elimination for an extended period of time compared to other litters.

Some praise its absorbency because 4–5 lb (2 kg) can absorb liquid and odor for up to 30 days for one healthy normal weight cat. It is important to lightly stir the crystals daily while scooping the solid waste, otherwise urine can pool in the box. When crystal litter is saturated, at the end of 30 days or so, it begins to smell and is visibly saturated. In comparison, over the same time period it may take 20–30 lb (9–14 kg)[citation needed] or more of clay or clumping litter, because it is necessary to replenish the litter that is removed when the clumped urine is scooped out. No replenishing is necessary with silica gel (crystal) litter.

Others have claimed that this litter gives them no warning when it is saturated and their cat left a urine puddle at the bottom of the pan, but as mentioned above, this litter will eventually begin to smell when the crystals can no longer hold any more urine. Also, as the crystals absorb the urine, odorlessly, they turn from white to slightly yellow. This is when a crystal is 'visibly saturated'. It is easy to determine when this litter needs changing because you can either smell urine (the crystals are over saturated) or you can no longer see any white crystals.

Crystal litter is extremely lightweight, especially when compared to heavier clay and clumping litter.

Silica gel litter comes in two shapes: irregular lumps and small beads. Sizes range from 0.5 mm to 4 mm.

Hmmmn I know silica gel isn't meant to be ingested. Could it be an issue if hoggies try to eat it?
