hi
kitty litter can work extremely well..... i really didn't want this to
be about that
this is a kitty litter without additives that's been tried many times
this particular brand especially
it's just clay, no additives....... in most cases, the very cheap kinds
of unscented non-clumping litter are just plain clay
you can even check the archives of this group or read at the Krib etc
etc you can read about it
it works well for gardening as well - instead of perlite or clay balls
