No, specifying that your cats are FeLV and FIV negative is par for the course. But for a cattery raised cat, this should be a given. Any breeder who produces FeLV or FIV positive kitties is lower than low. I always provide proof to my clients, but honestly, it just involves a simple and cheap blood test. What is more to the point for many breeds is testing for the HCM and PKD gene defect. That has become possible through services via Washington State University. Japanese breeders are somewhat slow on this, and I am discontinuing my breeding program for the time being. But FeLV? FIV? Beyond a joke. And before you post about backyard breeders, please remember that only five percent of Anerican cats have an identifiable breed.
