The vet sent this letter, which I think is really sweet and well-written. I mean, barfy, and I would have left out the word "special" out of an inabilty not to hear it in irony quotes, but it's a good letter of consolation and sympathy:
I am so very sorry for your loss of Henry. I could see what a precious companion he had been to you and how hard it was to say goodbye. He was lucky to have been your cat and so deeply loved. I hope the special memories you have of him help to bring you comfort now and always.
He was 15 when he died a couple of weeks ago - we hoped he would rally but it didn't happen.
He was a good cat! Grey and white and fat! Meowy, with a rebuking stare. Sometimes he'd spaz out and run away like a chicken. You could pick him up, and he'd sleep on the couch next to you if you stayed still enough. He'd let you pet his belly! He didn't hide under the bed all day! All very fine qualities.
