It sounds really hokey to me also. With feline vaccinination related carcinomas cropping up right and left the last several years, I only get rabies for my cats every 3 years now. I do the kittens series for FVRCP myself (I do rescuing, and have been hit with panleulopenia one to many times) of two shots 3-4 weeks apart. Are you in a small town? This reminds me of a dentist my husband saw many years ago, that said hubs needed to have his wisdom teeth out right away! It turned out Doc was taking a vacation, and needed extra cash. Needless to say, hubby's teeth were fine for 10+ years after that visit, and the Dr. lost a client!
