This is not the first book of this type I have read about vaccines, how awful pet food really is and alternative ways to keep your pet healthy. This book is very informative and has articles that relate to what I have found in other books by different authors, so there is a real problem in the pet food industry as well as with the vaccines and drug industry. Driscoll even gets into historical psychological facts about humans to show a correlation between human and animal side affect from drugs, vaccines, poor food and that modern medicine is not what it is cracked up to be. I have seen first hand what modern medicine can do to cats. I rescue, break up colonies and adopt them out. I have seen Revolution give cats seizures after only a couple day, high fevers for now reason appear after about two weeks for no reason. One of my cats has a burn from where I put the Revolution. This is a pesticide, I knew this, but I am having a really bad time with ear mites and was at my wits end. I have not used conventional anything on my cats in eight years and regret even this time. Revolution is a suppose to be safe and the conventional vet I bought it from thought I was a fool for waiting so long to use it. My cats are indoor only, but the rescues pose a problem sometimes and with all black cats I missed the ear mites in one. I pay very close attention to my cats and this is why I caught the problems. Most people put Revolution and their cat or dog and send them out the door. And, especially a cat, if it does not come home for a few big days no big deal. They have no idea the animal could have been suffering badly. I a dog they will probably run it to the vet and no one will suspect the Revolution is the culprit because the drug company says it is safe. Vioxx was said to be safe and how many other drugs are now under the gun for being not safe. Please get Dr. Pitcairn's book Naturally Healing for Dogs and Cats. Start with this and learn all you can about how to better the life of your dog and cat.
