It takes forever for the used litter to break down.
I like the trench method of composting for used litter.
Bury it and forget about it in an unused corner of the
yard away from veggie gardens.
Over in the Cat Forum, there has been talk of solutions for alternative cat litter. Since this does not come under the hat that I wear I leave that up to dear hubby.
Our daughter's solution was to get one of those fancy units that goes in the bathroom and is hooked up to
water. Other folks teach their cat to use the toilet.
