Fill your empty litter box with 3 inches of sWheat Scoop®, and pour 1 inch of your current brand on top. (It's okay if your cat mixes the litter. sWheat Scoop plays nice with others.) 2.

Entire contents should be disposed of in the trash, not the toilet. sWheat Scoop does not recommend flushing the litter into a sump pump hole that has to pump the litter uphill.
