My friend Gail got tired of buying kitty litter, so she came up with a way to not only get free litter but save on the recycling fees her city charges to pick up recyclables. She starts by shredding papers she would normally have shredded anyway such as bank statements, bank credit card offers, etc., then she mixes in some shredded newspaper. When she first introduced this natural kitty litter to her cat she mixed the shredded paper with her normal kitty litter. Now, she just fills the kitty litter box with her shredded recycled paper and empties it daily. Brilliant!
