Me again. I made an appt. with the vet for Sundance's Feline Luekemia shot and after reading more about this (Cat Fancy) has an article about Vaccine Induced Sarcoma's, I may cancel his appt. I am really afraid of the reaction. Sundance is an only cat and does not go outside, we have no others cats come into the house and my last cat lived to be 19 years old without any shots. I still don't know what to do, I just know I would be devasted it Sundance died because of me.
