The house can be re-built. Maybe you can send the pets out with someone? Some hospitals even make a kennel area for staff pets. Your wife might get an ok to put them in an office or something by agreeing to stay. It wouldn't hurt to ask.
Completely agree with CindyDawg. Please go the hospital to be with your wife, Dog Gone. I know someone who is married to a doctor that has to stay during hurricanes. She goes and stays at the hospital. I understand how you can't evacuate and leave her behind, but I think you will both be much better off if you are at least in the same place. Put your pets in the car and just go! If the hospital administrative staff are foolish enough to send you away, then she should leave and go with you. I understand why you wouldn't want to leave her behind, but think how she will feel if you stay because of her and something happens to you.
We'll ask. We're putting ourselves at risk for the hospital when some employees are just bailing. A little accomodation can go both ways...
I agree with CindyDawg-- some hospitals in LA allowed people (staffers and volunteers) pets in.
My tag line (for now) refers to the Dr. at Lindy Boggs who was the last one out of the hospital. He stayed to take care of all the pets people had brought and refused to evacuate until all the pets were evacuated.
Ask. If you don't get the right answer, ask again and work any angle you can. Such as you'll only let your wife stay if you can volunteer and there's a place for your pets. (You CAN bluff, can't you?...) ;-)
Take care and keep us posted.
