I think it would work. If it gets to be too much you could always bury it or use a dedicated composter. I once did this with a 5-gallon bucket with the bottom removed. Sank it halfway in the soil, set the lid on loosely, and I was able to use it for a long time before I had to pull the bucket and find a new spot.

Can't use S'wheat at my house, the ants got into it when we tried. I'm trying a sawdust based one (Feline Pine), it's very light and fine and clumps OK but the cat tracks it everywhere due to its light weight. Would be quite compostable though. I'm currently flushing since it's cold out but I may try the bucket composter in the spring.

Wheat based, pine based, pea based - I've used them, and I compost them, with the absorbed urine.

txcrusadr, I don't know what kind of system you have, but even now, in the winter, I compost the stuff. The system = scoop up the litter w/ absorbed urine into small paper bags (either store-bought lunch bags or whatever paper bags I can collect) and just toss the whole thing into the pile.

johnnieb, I've never added it directly to a garden bed, so I can't say whether your method would work or not. Maybe someone else here can comment on it.

so long as you're not eating the plants I don't see what the harm would be.

Thanks for asking. :O) Just started using the stuff but have a fussy cat so we are mixing it with the clay based stuff for now. Adding more of the wheat stuff every now and then so I figure in about a month she'll be into it 100%.

We have an ant problem so thanks for the warning tox. Will have to keep an eye on that one.

The wheat itself is a fertilizer. When you add urine to it it becomes a hotter fertilizer. Assuming you use it after the urine has dried, a starting rate for using it as a fertilizer would be about 5 pounds per 1,000 square feet or a scant handful under the canopy of smaller plants like roses. Just scatter it under the plant. Then watch the plants carefully for 3 full weeks to see how they respond to the fertilizer.

lynxe, the only reason I'm not composting it right now is laziness. And the fact that it's 8 degrees. OK, two reasons. :-)

I use ground corncob litter for three cats .
Found it at Wally World .
I called the company ( phone number on bag ) and they said ,
Yes , it is completely compostable .
My compost piles are very happy !
I like it much better than traditional clumping perfumed clay .

Your Waggies will love it in the Spring.

FWIW: I've read quite a few articles concerning flushing cat litter into waste water systems or using used cat litter as a topical application in gardens. There is evidence that toxoplasma-gondii is killing sea otters. I didn't want to provide a link to any particular article, but when Googling "cat feces + sea otters" there are many hits. Can anyone advise?
