Pre-vet program at a college is usually 4 years.
I'm not sure about the 4.0 gpa thing, but you have to have phenomenal grades.
Then you have to go to a vet school (like Bel-Ray in Colorado). I'm pretty sure that's something like 3 years.
Then a load of volunteering, intern work, etc. etc.
That's where I'm headed, too. =)
