I raise redworms and mealworms. The mealies are for the birds, the redworms are for the cats
I hatehatehate cleaning a catbox, so a few years ago, I bought some rubbermaid totes and about 3000 redworms and started an experiment.
Put in some nice loamy compost, added worms and some kitchen veggie scraps. Switched from clay litter to pine litter. When the litter box was ready to be changed, I dumped it all into the worm bin and added a layer of kitchen scraps and then another layer of dirt from the back yard. In about 3 weeks, they'd composted everything. That was too long to go between catbox changes, so I set up some other bins and started a rotation. I now have six bins that compost cat litter and four that froze outside.. oops.. that compost the bird cages.
When I have a tote full of worm casings, I put another tote on top of it with kitchen scraps and some loam, and wait for the worms to crawl up into it. Then the compost gets dumped into black garbage cans outside and left in the sun to heat sterilize. After a week, I dump 'em in the garden. The vegetables and herbs grow really really well.
Last year, I had too much to use myself, so I heat sterilized it and put it in plastic baggies and put it on CraigsList for $5/2lb bag. I sold all of them the first two days and made about $400. Each of my bins weighs about 30lbs when full, and I have 5 of them going at any one time. I sold about 3 bins worth.
It's made life much easier with catbox changes. It's not really a profit making thing for me. Usually I use my compost, or my friends do. It's an awful lot of work, so if you factor in the time I spend taking care of the bins, it's not actually a profit. That being said, the money was nice.
