veterinary medicine or zoologigy as a career and why?

Studying L2 Applied Science and Tech, wanting to progress to L3, however I am yet to decide on a career. I am also studying L3 Performing Arts and Circus and next school year I will be having a gap year to work on publishing my childrens book and other projects whilst working on restablising my own mental health. I have solid interests in both vetinary science and zoologigy but I would love for you guys to try and persuade me either way. Theres no garantee that that will decide it but it will be mighty helpful. :)
