Pat, I'm sorry to hear about the new pee incident. Wish I could help.

The smell of cat pee is difficult to get rid of, and if Galaxy can smell any, she will most likely go again in the same place. It's hard work having to wash everything so often. Can you hang it to dry outside?

I wonder if it would help if you spray something that cats don't like on your bed - I have no idea what it could be, but perhaps lemon or lavendar. It should be a smell you like yourself, of course.

Oh, just thought of something... instead of getting more plastic to put on your bed, you could buy one of those blankets that they use for beds in hospitals. I think they soak up pee, and I imagine pharmacies sell them.

What do think trickered it? Does the vet have any clue?

I send you positive thoughts, love and hugs. Hope you can solve it.
