Thank you for all of your good wishes, and sorry I didn't come back to update sooner.
Sadly Harry didn't make it.
Actually in the end we didn't even make it to the vet.
I was getting ready to leave and he was in his carrier on the chest in the hallway.
I went to check on hime one last time to make sure he was comfortable before putting him in the car, and it was obvious he was already fairly far gone.
I picked him up and he was floppy and unresponsive, so I sat down and held him wrapped in his blanket.
Less than 5 minutes later he squeaked, shuddered a couple of times, and passed away in my arms.
I am in absolute pieces about it.
He was only 3 years old, and went from eating, popcorning and wheeking to dying in less than 6 hours.
I took him to the vet this morning for them to arrange cremation, and the vet was kind enough to come and have a chat with me.
She suspects it was some form of serious underlying issue that cause major multiple organ failure, and that in turn caused his whole system to simply shut down. She did say that given how quickly he deteriorated despite clearly being in good condition, she doubts we could have saved him.
Sleep tight Harry
