I said "nurse" although its for animals... there is a movment to change "vet tech" to "Veterinary Nurse/RN" to sound more professional, but I really don't care either way (unless being labeled as an RN comes with a significant raise)

I could have gone "scientist" since I have a degree in climatology, but since I have yet to actually use it for earning any kind of wage, I felt that I could not say it was my job
