feline lymphosarcoma

[David Richard Harper]

I am a (herpes) virologist, and recently had a Siamese cat die of a rapid 
onset disease that may be related.  The first sign was a copious clear 
exudate from the anus, followed by oedema and necrosis of the rear half 
of the body, most notably in the legs.  Tests show abnormal liver 
function although pancreatic function continued.  Tests for FeLV were 
negative.  One week after onset, the cat was euthanised.  PM showed one 
ulcer in the large intestine.  He was barely one year old, and had been 
very healthy before onset.  I had wondered that some of the symptoms 
seemed similar to those reported for equine arteritis.  Any thoughts?
