I'm health-conscious. Or, at least, I try to be.

I try to eat simple and natural foods. I drink filtered water. When I clean the house, I try to keep the use of chemical cleansers to a minimum.

But it's very hard to live a 100% natural and chemical-free life. Many things that surround us daily -- whether it is food or environment -- have been engineered by human hands over the decades with the development of modern technology.

The life of pets is certainly influenced by the human world.

I do my best to give my dog and cat the best pet food possible; something that is nutritionally balanced and doesn't contain chemical preservatives. I also try to give them as little chemically-treated surroundings as possible.

But again, it's very hard to give my pets a 100% natural and chemical-free life. Once they step outside, they are surrounded by car exhaust gas, pesticides, herbicides and so on.

All I can do is raise my consciousness about a healthy lifestyle for my pets (and for humans, too), and help my dog and cat build strong immune systems to combat harmful substances around them.
