We are so sorry to hear about your poor Koko. At one time we had Six Siamese at the Found Cat Hotel and it was a gut wrenching experience to watch these beautiful creatures of our all mighty Lord God above pass on.
Koko will be in good company with all those Siamese Cats and will let you know that he is all right.
Knowing our Siamese I know that they are in Jamaica in the sun and they will find that spot where you will be together furrever.
One Fine Day
