If you have a cat or a dog, you should look into feeding them raw carnivore (raw meat, raw milk, raw eggs, etc).
Dr. Francis Pottenger demonstrated in his tests with 900 domesticated cats, over a decade, that cats developed strong bones when they were fed raw dairy and raw meat.
Also, he found that sick domesticated cats with osteoporosis reversed the disease when they were fed raw meat and raw milk.
Edward Howell repeated the same clinical tests with rats and received the same results.
In his tests, he shows that cats fed raw meat and milk are faster, stronger, more coordinated, more energetic, have wider faces, stronger teeth and bones and larger, healthier babies than cats fed pasteurized milk and cooked meat.
The cooked meat cats were unable to reproduce after the 3rd generation and most were void of sexual interest.
On the other hand, the raw meat and milk animals continued to reproduce healthy offspring generation after generation.
Pasteurized food = Dead food
Of course, you should also not vaccinate your pet.
