Oh no, Georgia, I'm so sorry.

I think you are right to not leave him there. Being away from home is quite stressful for kitties - especially if there is no one there with them. Giving fluids is a piece of cake and I know you will be able to do it for Mishi. I sure hope they help stabilize him.

{{{hugs}}} to you and positive thoughts and prayers going out for Mishi. I know you will be giving him extra snuggles this weekend, so please give him some for me too - poor boy.
