Since all his tests have ruled out any sort of medical problem, it does sound behavioural. If Melinda's idea of earth in a litter box doesn't work, you might get him used to a harness in the house, and then take him outside on a leash to see if he will do his business there? I can well imagine how you're at your wit's end. No, you should not have to live like this, nor should your other pets be deprived of a nice soft spot to sleep. As a last resort, maybe you should consider sending him to a rescue place.
