We're not talking about regular clay kitty litter. Do you really think silica gel was invented to hold cat poop? The beads are made out of the same stuff.Ok I don't get why people would trust kitty litter to humidify potentially thousands of dollars worth of cigars when beads are more than affordable. I understand you can train the litter but I just can't imagine trusting that much money for something designed for cat feces.
I for one find beads can be very hard to get perfect. Litter is actually more effective to work with because it has a larger surface area.
