I tend to agree with this comment. It seems there are more and more applicants each year so veterinary school isn't becoming any less competitive, and do you
really want to go through another application cycle if you don't necessarily have to do so? Personally, I would take MWU and run especially since you are OOS everywhere you apply; no astronomical attendance cost differences involved that play into the decision.
I'm definitely not saying you aren't capable of being accepted to Auburn next cycle because no vet school waitlists anyone they cannot see attending their program. I would just want to play it 100% safe and go ahead and start in the fall at MWU.
Just my two cents
