Brilliant!
I have four indoor cats, and wouldn't use any other cat litter. I've been through loads trying to find one that worked for me. I thought I had found it in another litter that Zooplus sells but Catsan Hygiene is much better. It absorbs urine like nothing else - even with four cats it can last three to four days before it starts to discolour and break down. Even then, it doesn't get wet and it never sticks to my cats' paws or tracks through the house. The only time it ends up outside the tray is when my cats jump out and kick a bit out with them. But because the granules are large, they are easy to deal with. Fine, clumping cat litter used to drive me nuts. To make it easier for cleaning, I use tray liners and a puppy pad underneath (my cats are overzealous diggers and always put holes in the liners). The result is that every three to four days, all I need to do is tie up the liner, bag and bin it, wipe the bottom of the tray with some disinfectant and fill back up. Much less hassle than I've ever had before. WELL worth the money.
