Thank you Zara. I think Jack was older than i was told and his time was up. It took me by surprise until i realized what was happening.
I've just hang the wash on the line and looked at Jack's grave and his Alaska in the greenhouse trying to get a (imaginary) signal from Jack.
I'm not sure where to go from here and what's best for Clive now. Jack and Clive very much bounced off each other. There was a rivalry of who gets out first and in which playground between them. One always wanted to be where the other had been before which involved a lot of sniffing.
Clive's been quieter since Jack started to make his way to the rainbow bridge so maybe it would be better not to adopt or rescue another Syrian to live in Jack's Alaska and let Clive live the quieter life.
I could move Eddie into Jack's spot which would make interacting with Eddie easier for me.
A lot of people would say, give yourself time to adapt to life without Jack but i don't function that way. It's like i have this need to fill the hole a departed hamster has left to make things more acceptable, easier to cope with.
The garden hamsters will always be part of my life but in a different way from the living ones. I'll never stop missing them.
