Oh Henry ~ I'm so sorry you have lost some of your stash and going through this delima. Since you have had the house checked by professionals, if I can give my 2 cents -
Sit your friend down and explain if she is to continue to live there some rules must be followed.
#1 Your room - your space - - - MY house - MY rules
#2 Keep your room CLEAN
#3 If dog is allowed to stay in house, he/she can no longer eat off floor in bedroom. Must eat in different room of house that IS NOT considered living area; ie utility or laundry room.
#4 If these rules cannot be followed, in order to keep our friendship in tact, maybe we need to dissolve this living arrangement. (Give her 30 days to find somewhere else to live)
That's just my 2 cents worth :wink:
