Clump "N Flush - corncobs The Andersons.

I currently am using World's Best Cat Litter. It is flushable and septic tank safe. Toot is on Amber stage and loves to push a lot of litter down the hole before going potty. Sometimes I have to flush a couple of times if the litter has been sitting in the toilet for a while. It sticks some to the bottom. It's OK at clumping, but from what I've read fushables don't usually clump as well as hard clumping clay based litters. If you go to the website you can print out a rebate for the small bag. Buy at normal price and send in UPC code, receipt and rebate form to get a check in the amount of the 7-8 pound bag. SO this is a great option for people who are looking into different types. Normal price for the small 7 pound bag is about $8.
