Most of the litter's I've bought are "scoopable" - and I've also used kinds that are "clumpable."Scoopable
means that when your cat pees, the pee is simply absorbed into the crystals/pellets/etc - but you can still "scoop" essentially, because when you scoop - you remove the feces.
So you can scoop the feces out, but the urine is absorbed into the litter.Clumpable
means that when your cat urinates, it forms a hard clump so when you scoop out the litter box, the urine clumps and the feces are removed - and all of the remaining litter is clean.
See the difference? I hope that description makes sense.
So all clumpable litters are scoopable, but not all scoopable litters are clumpable. Gosh, that reminds me of those riddles that you have to solve in IQ tests.....
Either way - I'm no litter manufacturer, that's simply my "experienced" opinion....
