Tiger's ultra soft poops were not getting better so I figured the
Acidolphulis was no longer potent.  Sunday I bought a new jar (which was
kept in the health food store refrigerator).  That afternoon I added
some to the food.  This evening he presented me with a perfectly formed
poop (in the litter box of course).  The lesson learned is that
acidolphulis must be refrigerated and current.  When the bottle says
"best by" they mean it!
