Well here’s the thing, you ARE an animal. All humans are animals. However, the particular chemical that makes you an animal, rather than a plant or a bacteria, is DNA. DNA is a chemical molecule that happens to have lots of information stored in it, and whilst ALL living creatures have DNA, they all different enough to make the many different living creatures we see.
You’re stuck with the DNA you’ve got, and no chemical that we know of will turn you from being a human animal into a different kind of animal.
