I have moved this to the Rainbow Bridge, as it seems a bit more fitting in here..

So sorry Mo, You have had a terrible time the last week or so. Unfortunately, it is something Suz and I can relate to having also lost 2 ferrets within a week in the past and we know just how heartbreaking it is.
As I said on Mercia, there is nothing more you can or could have done, it is just one of those nasty tricks of life. This is a bad time of year for older ferrets.
I know it is a lot easier said than done, but don;t beat yourself up, you did the right thing, and made the hardest decision you have to make when owning a pet, at least he died with dignity and not in pain.
