Can I Change my Major Prior to Committing (I've Been Accepted)

I was accepted with the major of Veterinary and Biomedicak Sciences. However, I want to switch my major to Biology. I'm not yet committed but I've been accepted. I do plan on committing but hopefully after I can make this major change. i don't think it's a competitive program but is it still feasible? I contacted admissions office and I'm waiting for their response.
