K, I hear you on the mousey expense...The same happened to me.. Very costly. Then the little @#$% crawled into the motherboard of my stairlift and I had to replace that.. Another very costly item.

I found out, later, that they were living comfortably in my attached garage. they're gone now and I have taken measures to keep them gone.....I hope!!

Sorry about all your other unexpected expenses....that sucks.
