Cat litter composting

August 11th, 2009

Bentley, over at redwormcomposting.com, has a new post up about cat litter composting, and his experiences with it.  He started out trying to compost cat poop, but also wanted to know if the compostable litter he was using could be processed by redworms.

Initially the composting seemed to proceed at a very slow rate, with the volume of material in the bin remaining relatively stable. Strangely enough, after my last big addition of cat litter waste (I tend to let it accumulate for awhile before adding it), the level of material in the bin seemed to go down quite quickly all of a sudden. I also noticed a lot of mushrooms growing in the material (as you can see in the image above) just afterwards.

Yesterday, when I was taking some pictures for this blog posting, just for the fun of it I decided to have a peek at the material in the bottom of the bin. I was curious to see how well decomposed it might be. When I pulled up the compost access door I was shocked to see a bunch of fat, vigorous Red Worms wiggling away. Upon closer examination I discovered that the material was not only loaded with worms, but it’s also contains countless cocoons!

Good stuff!  Read the whole article.  Also, you may be interested in my interview with someone who composted dog and cat waste.
