Clay litter does such a number on our environment! Its great to learn that there are now corn and wheat based kitty litters! Some of the benefits of wheat/corn litter over clay is that they are grown naturally and aren't causing our land to get torn up by people digging for clay. It has less of a carbon foot print while being "produced" and they can help cut down on the use of plastic bags. A lot of people scoop their dirty kitty litter into plastic bags, which we all know is terrible for the environment. It takes 100 years for a plastic bag to decompose. But the corn and wheat based litters can be flushed down the toilet! I have 5 kitties and have always been very picky about my litter because with having 5 kitties its hard to keep the litter boxes smelling fresh. I've tried dozens of litters and only found 2 brands that I felt actually work on keeping the boxes from reeking. I was originally going to try Swheat Scoop litter (which I still want to try) but the pet store was out of stock so I tried a corn litter. I was afraid that my bathroom was going to start smelling back but surprisingly it hasn't! I love that I'm not wasting plastic bags and I actually scoop the litter boxes more frequently because I just scoop them every time I go the bathroom, that way I'm not wasting extra water! I give corn litter 2 thumbs up!
