Just exactly why do I need kitty otter?? I recognize the other things as being pushed by certain types (ahem Alex) but what the heck is the kitty litter for?
Kitty Litter. . .are you referring to diatomaceous earth? I would put it among the “end times” must haves but use it now.

You are thinking of bentonite clay, which also has medicinal uses.
