It's such a relief about the tests. I'd never heard of Dr Addie before. I presume she's a researcher at the University of Glasgow? When the vet rings me I'm going to broach the subject of diet again. He'll probably just think she's a nutjob, you know how vets can be, but it can't do any harm and might do some good. At worst Lulu will just be deprived of her favourite grub for a few weeks. I'm assuming (without seeing the book yet, obviously) that I'll give diet a go for a couple of months and rethink the extraction after that.
