9 Month old Siamese...ate laundry soap!?!

Question
I have a sweetheart of a Siamese, 2 actually, They knocked over a bottle of Laundry soap last night, and walked in it.
I washed both cats paws, and put them in my room while I cleaned up the mess.  But my female is not coughing and sounding very raspy.  I am stuck at home today and to far away from my vet.  I called but they are not open yet.  I tired giving her some fresh water, but wondering what else I can do, maybe some milk?? I know cats should not have milk but I thought it might help her stomach.  When she tried to purr it sounds broken up.  I am worried about her!
Any advise would be wonderful.  BTW it has been about 10 hours since the spill, I must have missed some on her.

Answer
Oh Boy!  give her some Benadryl about 25 mg...If you don't have any then you must find a ride to any VET office.  Please, her airway may be closing off.  The Benadryl will reverse this for you... Go to a neighbor and see if they have any benadryl...OK

Let me know what happens.
