Ryan over at Unplggd posted about the NatureMill kitchen composter back in February, and we noted they also offer a pet friendly version. Composting cat and dog waste isn't recommended, since their waste can harbor E. coli bacteria. But supposedly by using enzymatic "Super Digester Concentrate" additives, some believe pet waste can be safely composted in the backyard to reduce waste matter and to use on anywhere but edible gardens or flowerbed. Below the jump are some retail and DIY solutions we found online...
CityFarmer has a step-by-step tutorial showing how to create your own dog-dooly composter with a plastic garbage bin (resulting compost should not be used in the garden).
"Within 48 hours, the septic tank starter, (which is non-caustic and promotes natural bacterial growth) will have begun its work and you can add more dog doo. You can then begin to add it daily. This waste biodegrades and flows into the subsoil."
The retail version of the idea above is the Doggie Dooley, described as a "miniature septic tank, utilizing enzyme and bacteria action to automatically reduce dog waste to a ground absorbing liquid." Works with 1-4 dogs and retails for $89.95. A more affordable PetSafe Eco Clean InGround Waste Digester PLUS is available for about $20 less.
And then there is NatureMill's compact version which is meant for outdoor use and can be used with scraps, cage shavings, and pet waste. The composter is priced at $399 and can handle the waste of 2 large dogs, or 4 cats, rabbits, hamsters, snakes, ferrets, or other small animals . We're not exactly sure why this model is priced so expensive, but some of the cost might be due to the above ground design.
