Sorry for not replying earlier Leigh - Chris has been dealing with the vets and got in late so i didn't have much new info to post.
Holly is a lot better tonight and it's almost certain that although she does have KC, it's no-where near as bad as the original vet lead us to believe. Holly had gotten hold of an airfreshner that is normally stuck to the side of the 6ft bookcase in the lounge but when I'd turned it on I must have loosened it's grip and it fell off at some point. It was one of those circular ones that you can turn the outer cover round and the disk inside gives off the smell.
She'd been outside in the garden and then came in, ran upstairs and collapsed in a heap on the bed. The senior vet thinks that the allergic reaction was getting worse and when she ran upstairs it was just too much for her.
I've got to go in on Friday - when I've got someone to sit with the kids - to sort out the insurance claim forms so that I'm claiming for the right thing and to avoid any confusion. I've refused to pay the consultation fees and told them that unless the anti-biotics would have been prescribed anyway then I won't be paying for those either. Neither will they be going on the insurance bill.
She's to go back in next week for blood/urine tests to check Liver and Kidney function and if she's fit enough for a cardiac ultrasound - if she's not up to it then, she'll have to go back another day for it.
Thanks for your concern, and thanks to Delores for the thought of the kisses

Holly loves kisses and in other circumstances she'd be in the car to come and collect them personally

I'll let you know how we get on Friday,
Fiona
