Back on the 9th when I was asking for help in trying to resolve my cat's
problem; I want to thank all that responded and gave me advice. I tried
emptying some of the litter as I found out that some cats (when they get
older) don't like to use as much. I now put less than half in the box
and he seems perfectly contented. It's been over a week and "TJ" has
used his litter box properly. He has not (at least so far) placed feces
on the floor.

Again; thank you ALL!
