I'm just seeing this now. I'm so, so sorry for your loss and I know how heartbreaking it is to make that decision but I do believe it's the last act of love you could have done for him.
RIP sweet Ming. The Catmobile Gang will truly miss you and the bagpipes but I'm sure that you are strutting your stuff in tartan all through the streets of the RB.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand and strawberries in the other, body thoroughly used up, totally worn out, and screaming WOO HOO - What a Ride!
Sometimes the most real things in the world are the things we can't see
Until one has loved an animal, part of their soul remains unawakened.
