Cat Poo Composting with Compost Worms in Soil

Hi everyone,

I'm planning to have a covered, plastic cylinder half buried in the ground, and put 500 worms or so inside. After about a week of letting them settle in, I was planning to put my cat's waste in there for them to process. My plan is to put it in a shaded spot, amongst ornamentals.  

Related to this I have 2 questions I'd like some help with.

1. My guess is that the conditions in the compost would tend towards acidic. Would adding a little lime once a month be a reasonable way to try and maintain an acceptable pH?

2. As for the kitty litter, that is definitely very acidic from the pine and urine, could I add this to the compost as long as I add some lime together with it?

Any help would be great .

A previous thread on this topic with an interesting link how a young boy set up such a system: https://permies.com/t/47541/Bokashi-worm-composting-pet-poo

You could set up 2 systems, one for the poo and another one for the litter.  

You could test the pH level by preparing a sample following the procedure mentioned on page 4 of https://www.dot.ny.gov/divisions/engineering/technical-services/technical-services-repository/GTM-24b.pdf
No need for an expensive pH meter, a pH test strip, although not very accurate, will give you an idea whether adding calcium carbonate is necessary.

Make sure the bin or whatever you will be using has good ventilation. Ammonia gases will kill worms
