I had enough training in the health sciences (masters in veterinary physiology) that even though it was a long time ago and I have forgotten almost all of it, I'm not intimidated by the subject matter or by anyone in a white coat. My last several years have been spent intensively learning whatever I could to help my cats. It's pretty much my hobby and it's empowering. It's obscene to me that veterinarians do not learn what we need them to learn about basic cat health care and then make no effort to educate themselves after they graduate either. But it's within our grasp. The age of the internet and topical forums have helped a lot.
School was mostly hypothetical for me. Now that I have the practical applications (caring for my cats), it's much more real, I'm more interested, and it's sinking in better.
