I'm glad you brought this up. I recycle everything faithfully and was just thinking about this very subject while I was scooping last night. I use the clumping litter also and have 7 boxes that I clean twice every day. That's 4 Wally World bags a day. I even have a couple of neighbors saving bags for me. Actually, I kind of considered my reuse of the bags as a form of recycling.
