Most cat litters (flushable or not) are made from clay. Exceptions would be Feline Pine, Swheat and Yesterdays News. I spilled clean cat litter on my basement floor,then the washer overflowed, clay plus water equals slippery mud. Took forvever to dry out. I opened the basement windows and set up fans. Finally dry, I was able to scrape up the mess and dospose of it. Never ever ever put anything from a cat in the toilet. You will definitely ruin your plumbing as Dan 1954 explained. I scoop my cat box (I now have just one cat) every morning. Put the scooped stuff in plastic grocery bag, twist and put with my household garbage for twice-weekly pickup. May be bad for the landfill, but what else can I do with it?

I, too, use the World's Best corn litter. It does have some residue dust...but far less than the clay litter. I switched to this litter as soon as I discovered it. After watching my "little" darling...[seen below creating a Kodak Moment in my laundry basket]...cleaning herself after a difficult "movement"...seeing her helplessly ingesting some of the clay...I went on a hunt to find a litter less harmful to her intestines. It took her no time at all to adjust to the corn and...to me...she seems much happier with it. She'll be 14 this summer...and she weighs a healthy 12 lbs. So...the old adage that you can't teach an old cat new tricks obviously doesn't apply to my furry companion. ;-) Anne

Four indoor cats here -- and one litter box! It is kept in the unused master bathroom bathtub! A hard decision -- but that spot has worked out SO well for us. Our litter box must be lidless because our cats literally outgrew the lid itself! LOL! The best thing of all is that the box cannot be seen because of the high walls of the tub AND the fact the tub is located behind the "swing" of the door so I love it! And the tub is easy to clean too! Our policy is scoop out the box several times during the day -- into a grocery bag, tie it shut, and stash in a tall brass garbage bin (which also has a medium sized plastic bag) that JUST fits in a empty slot between the vanity and the shower. The garbage can is emptied once a day out to the main outside garbage can. We were lucky that a litter container JUST fits in behind the brass bin too! So the extra-large main container of litter sits in the garage -- and the DH fills up the one in the bathroom. The scoop is kept in a pretty garbage bin just under-and-behind the toilet -- so it is out-of-sight too. But still handy! Along with a brush-and-pan to sweep up any scattered litter. And a deodorant spray like Febreeze (which works great BTW!) I would dearly love a better spot -- but this house has no basement nor a laundry room so this system has worked for all of us! Jan

My DD used one that was made by Arm and Hammer I think.She had a septic tank and it never caused any problems.You might Google and see what is available.I know there are quite a few out there. I keep a bucket (an empty one that the littler comes in) lined with a plastic bag next to the litter box and scoop every day into that and snap the lid back on.When it's full just remove the bag,tie it up and take it to the dumpster.I also put one of those stick up air fresheners in the bucket,under the plastic bag,and that helps with any odor problems.
