You know Gary, Medusa is absolutely right there, spot on. And gee those Siamese can indeed be stubborn I know I recently got my 4th. Please know you always did your best for them and even not forcing him to be picked up and taken to the vet was doing the best in his book. Maybe he just felt it was his time and you and nothing was going to stop him going. And he didn't want to upset you with a long drawn out painful good-bye.
Please accept my sincere condolences on your loss, he was a handsome beautiful boy and magnificent specimen of his breed.
And yes he did have the best Dad in all the world.
RIP John Hancock
Sleep easily Gary, your conscience is clear.
