Thanks for the question. While it is possible to buy pet waste composters, but you can make your own. Find a 5 gallon (or larger) bucket with a well sealing lid. Cut the bottom of the bucket and bury it almost entirely in your garden (away from any places that you grow vegetables and/or children/pets may play). Put your pet waste into this container (ideally unbagged) and sprinkle with bokashi. Repeat. The life in your soil will do most of the work so that you can keep adding pet waste on the top and you should see the level continuously going down. If you should fill your container, then pull it out of the ground (leaving the fermented waste behind) and relocate. Cover the initial area with at least 6 inches of soil.
Note that although the bokashi composting process will help to kill the harmful pathogens found in pet waste, it is recommended that you bury the fermented pet waste at least 2m from any areas where you grow fruits or veggies.
Happy composting 🙂
