He died.
We didn’t have the luxury of time after all.
On Saturday evening he took a nasty tumble and all of the pharmaceuticals the vet could provide weren’t touching the pain so there was only one choice left.
If you’ve followed his adventures here, and he’s brought even a tenth of the joy to your life that he has brought to mine, then I am glad.
If I write about new trips without him please don’t think I have forgotten him. He will always be with me in spirit, and what a spirit it was.

I may have asked this before, in which case forgive my dodgy old memory, but have you ever written up or blogged Shakey’s story with you from the start? If so, would now be an appropriate time to give it another airing, with a link on Twitter for all his, & your, many Wingman friends?
Very sad to read this.
