Do indoor cats really need shots? I have 3 cats that never go outside...or even try to for that matter. What kinda deseases can a cat get if they are never exposed to the real world outside of harm and desease? I have 2 "purebred" Ragdolls. I have read two books on these cats...and both stated to use only "killed live virus vaccinations only". I just read a scary article at a holistic vet site that was titled "Are shots helpful or harmful to your pet" from a 30 year vet. The article stated that they did more harm to animals than good. They only recommend giving a rabies shot only if required by law in your state or country. I need some opinions from cat lovers here. What shots do you give your animals....and do they need them if indoor only?
