Comparing snakes to horses, dogs and people, is like comparing lollipops to bath tubs. If you wanna take that stance, then i'll counter with: well people have different metabolisms, why can't snakes? Same goes for dogs. Not every GSD/retriever/apbt grows EXACTLY the same. My hypo is almost twice the size of my lesser even tho i got them at the same time. Shes not fat by any means and my lesser isn't skinny by any means. We're talking about only bp's here, other species are different.
