bet there are plenty of similar problems which don't make it to the PT board.
I am finding this to be all too true. You would be surprised at the number of people I have talked to who have this problem (and they do not know what to do either).

So anyway, at 9 p.m. last night (25 hours after I put Sterling back in the large cage with the empty litter box) he finaly gave me the all important sample. I labled the bottle and placed it in the 'fridge. It will go to the vet first thing this morning. I actually find myself hoping that they find some remaining medical problem that we can try to treat.
