We've used clumping litter for years, but always the unscented. Vet once told me that some cats develop allergies or reactions to whatever they use to scent it. And since we have a septic system, flushing it down the toilet was never an option. The only thing that plastic grocery store bags are good for, is used cat litter, and it goes to the landfill with all the rest of the trash that is picked up.

My RB Meezer Ming taught himself to use the toilet - only to pee tho. I think he just liked the noise of the tinkle! Dummy never learned how to flush when he was done tho!
