Dear Dr. Varis,
Thank you so much for your help in funding treatment for my Geoffrey's renal lymphoma. This is the third cat I've had within the last twelve months to be stricken with a 
catastrophic illness, I was in near panic about what to do.
I simply could not have funded treatment for a third desperately ill cat. Again, many more thanks than I can put into this letter.
Sincerely,
Lisa Ledlow
