You could find a hundred ways to compare human and animal patients, but that wouldn't be fair to the humans.
Growing up I was fortunate in that we always had animals and I was able to spend a lot of time outdoors. Then as a teenager I spent 18 months working for a veterinarian, because I thought that was the field I would pursue.
However, life happens and time passes fast; then you go into an occupation that you know is stable and will always be needed.
After graduation maybe I can find a place of employment that affords us a little hobby farm with some goats and chickens or we can adopt abused animals. Plus coming home to animals after working with people all day would also be a great stress reliever.
