Very touching report. I much empathised with you when reading, as I know how sad it is to lose a beloved pet...
My wife and I have lost our two cats Findus and Lola (Lola died this Feburary, just like Lucy) in the space of not even two years, Findus to an unknown illness, and Lola to a nasty and terminal cat virus that had spread in the neighbourhood, and we still sometimes suffer from the loss. I even shot a little video on Ruadh Stac more this May to dedicate my Fisherfield round to the two of them.
14 years is quite an age, I'm sure your loving care was a big factor in that! Beautiful photos of her through the ages, she seems to have enjoyed the hills very much. I will definitely say "hi" when it's Ben Vorlich's turn in my Munro round and stay a while longer up there in her memory - and I hope the good memories you have of her will prevail over the sadness in the end.
