I agree, not a big fan of the changes Feline Pine made to the clumping formula. It's like half ground up instead of sawdusty. I have also used "WBCL" and it's great. You can find it on sale often, but otherwise it costs a little more than FP. A bag lasts a long time (I have 4 boxes and two kitties). I just bought a bag of Arm and Hammer Essentials clumping and it is "100% corn fibers" but I have not opened it yet. I tried a wheat type once, but I must not have been too impressed with it because I didn't buy it again. I think it was called "Swheat Scoop".
I live in the sub-tropics off the SC coast, and we have all sorts of bugs, but I have not seen any in or around the LB's whether I use FP or WBCL. Two of the boxes are on the screened porch, so if bugs were an issue, they'd show up there for sure.
