I do believe that in "gay veterinarian paranormal romance" you have invented a new genre. I tried googling that and got nothing. I found an erotic M/M book with a vet in it but it's realism (or as realistic as erotica gets.) Here's a general list of gay romances you might like as a substitute: http://www.goodreads.com/shelf/show/gay-...
only do it if you like chemistry, biology, physics and math. in the first couple of years, vet school is nothing like working as a vet. although you will learn about animals, during this time, particularly first year, its mostly chemistry and science... and most people who drop out will drop out in the first two years because of this - they realise you dont just sit there learning about pet anatomy and playing with animals all day.
it is a lot of hard work.... theres not just a lot to remember, but theres a lot to work out too in the chemistry parts.
if you like general science, however, go for it. its extremely rewarding.
go to some university web pages and check out the first and second year compulsory subjects for vet science.
if you like the playing with animal side of things more than the science you can always become a vet tech or assistant.
ive been to school for four different things. the most important thing is do something you absolutely love - then you will naturally be interested and naturally be good at it. dont do it for the money or prestige or you will fail or be miserable.
