Stinky cat litter tray, sodden clump of yuk at the bottom, know the story? I did.
This stuff is totally different, it just sucks up moisture and even dessicates (mummyfies LOL) cat poo into the bargain.
Basically the tray is dry, several weeks. I scoop out the solids and it looks pretty much as new.
As it ages it will go yellow or less opaque whiteish than when new, but it keeps on working.
When you do change it, the bottom of the tray is bone dry.
I only change it when it begins to smell a little, that is how I know its wearing out.
Otherwise no smells, no damp odours, its a miracle.
As I say I swear by this, I love it, the cats are much happier, used it now for several months and converted friends over to it too.
Just clean and disifect your tray before filling it with this, you can mix it with normal litter if your cats are fussy and need a slow changeover, but mine went to it like a duck to water.
And remember it lasts weeks, not days, thats a LOT of less bags of HEAVY wet litter to dispose of and even better, no carrying it home from the supermarket, Amazon delivers :-)
