If you want to be a vet you're looking at 4 years to get your Bachelor's degree and another 4 years in vet school getting your DVM (Doctorate of Veterinary MEdicine), plus you'll do internships and you'll have to taking a licensing exam before you can start practicing.
If you want to go to a community college first, I'd actually work backwards.
1st - decide what college you might want to go to for your Bachelor's degree and DVM degree. Colorado State has a good DVM program so you could go there for both. http://csu-cvmbs.colostate.edu/Pages/default.aspx
2nd - meet with a counselor at the college you'll go to for your Bachelors & DVM to find out what community college they'll accept transfer credits from because the last thing you want to do is spend time and money taking classes that won't give you credit towards your Bachelor's degree. Pick your community college based on this information.
3rd - get an idea of what you want to major in for your Bachelor's Degree (biology is always a good one for future vet med majors)
4th - get a printout of the classes needed in order to obtain your bachelor's degree and take as many of those classes as you can at the community college.
While you're earning your Bachelor's degree, you'll want to take opportunities to do internships or volunteer at: zoos, animal shelters, vet clinics, etc. I would definitely suggest volunteering/interning at a vet clinic to make sure being a vet is really what you want to do because 8-9 years of college is a major commitment of time and money. I thought I wanted to be a Vet until I volunteered at a vet clinic.
On the other hand, if you want to be a Vet Tech, just find a community college that has a vet tech program and take their list of classes. Bel-Rea and Community College of Denver both have Vet Tech programs. Just keep in mind that an associates degree in Vet Tech is NOT the right path to becoming a vet. Vet Tech is a technical certificate degree and only the core classes will transfer for credit to a Bachelor's degree. The actual Vet Tech classes will not transfer for credit for your Bachelor's degree.
I hope this helps.
