The poor thing was in such agony, his kidneys had shut down and because he had gone past a certain point he had no chance of surviving the surgery that needed to be done.
In hind sight now (oh how I wish we all had the ability to have it before we do things, or in my case don't do things), I should have taken him to the vet 2 days earlier, and then the outcome may have been a little different, but maybe not. In any case I didn't have hindsight, and now Zues is kept in a special corner of our hearts. (And of course our picture photo albums as he is in there quite alot!).
