That is just it - you can't. I have had 2 cats 'go' - one by euthanasia (FIP) and another dying in my home (cancer). It doesn't make a difference. They were both equally awful and devastating. In the end, there is no good 'end'. Sadly, it is just an (inevitable) end.Partly though, there's this feeling of incompleteness.... If I could rewrite the ending...
