First, Kirsten, welcome back! My three siamese have gone to the Bridge. Thai pased away due to old age. I think she was the oldest cat on this thread! She passed at the age of 22! My second died from a blood clot in an artery. Her name was Frederica. My third siamese,Ming, Was hit by a car. I was very lucky in respect to viral diseases, my kitties seemed to live normal lifespans.
