Thank you - I do already in a way - caring for him for the last few months was something I did gladly, as you would do to improve the quality of life of anyone you loved while they were nearing the end of their life - but it was a round of alarms set for medications and fluids, constant trips to the vet, getting more and more fussy about food and trying to find things out of the limited selection of renal foods that he would tuck into, getting thinner and thinner, frequently on antibiotics for UTIs, piss and shit and in the last few days, blood all over the place.
I am at least content that he was very happy and treating him for everything was worth it up until a couple of days ago, and that we did the absolute right thing today. I wish he could have had longer, but at nearly 18 he'd had a good innings and a very good life full of love and comfort, and we knew it was coming so there is no tragedy or shock involved at losing him - just sadness and missing him.
He was the gentlest sweetest thing, a very special creature, who showed his love to us generously and received our love with purrs and headbutts and Siam/OSH "WAAAAAH"s.
