I'm going to preface this comment by saying that I pulled most of this information off CSU's website.
How they choose who to admit is a bit of a broad process. CSU refers to their application process as holistic and as such I've never seen them publish any kind of a system or heuristic where certain aspects of an application are given weights/points compared to other aspects. I saw on their website that their final decisions for this cycle will be based 50% on your application and 50% on your interview, but there was no further break down beyond that.
There is no minimum GPA to apply, but it says in their website that applicants with below a 3.2 tend to not be admitted (though of course there are always exceptions). Every application with below a 3.4 is sent to early academic review during the admissions process - the goal of this review is to make sure that applicants still appear to be capable of handling the rigorous academic demands of veterinary school. If applications "pass" that academic review, they're placed back into the regular pool and evaluated the same as every other application in that pool.
CSU tends to value things like good communication skills, civic involvement (volunteering), and leadership skills in addition to the veterinary/animal experience that veterinary applicants typically have. They definitely put together very diverse classes from what I've seen.
They also take into consideration extenuating factors that may have impacted you throughout your pre-veterinary education - things like history of low income, needing to work to support yourself/your family, history of abuse, speaking English as a second language, etc.
You may find some pages from their website helpful (the first link has a link to their veterinary admissions philosophy at the end of the page, which I encourage you to look at):
I should also reiterate that I'm definitely not involved in admissions in any way shape or form, so if you're told something different by CSU please take their word for it.
