This vitamin is toxic in high amounts. Cats fed too much liver or fish will develop vitamin A toxicity which is life-threatening. Vitamin B6 may be important for stopping viruses. A researcher at Purdue University has shown that adding vitamin B6 to FeLv and lymphosarcoma cells in culture dramatically inhibits their growth. We can assume that our pets have as many or more.
Chemicals are in our food, water and air.
The question of whether combinations of chemicals we routinely eat and drink cause cancer has never been addressed in scientific studies. Because of their smaller size, our animals are particularly susceptible to chemical exposure. Dogs and cats eat animal-based diets. Unfortunately, some of the most toxic chemicals in the environment wind up in animal fat. Dairy products and meat are the primary source of pesticides in our bodies as well as our animals'.
