Hi Rockabilly, glad to hear you and your Grandmother lived to tell the tale!!
Sorry bout the bumper on the head and the crushed house though.
What was it, a storm? tornado?...
I think your cat will come back. From experience, I find they usually find a safe place to hide pretty close by but won't come out for 2 or 3 days...until they think its safe again. Then, hopefully it will be hungry and will find its way back home again.
hang in there!
