Good question! I think part of the addiction involves there being so many different beautiful morphs available, and you want to have a nice, varied collection, whether you intend to breed them or not. The other thing that comes to mind is that snakes are really pretty low-maintenance as far as pets go, so we always know we can take on one more, and it won't be that much work. Between my own snake collection and the hatchlings I still have for sale, I have close to 80 herps right now, and it's really pretty manageable. But can you imagine having 80 dogs, cats, horses or any other more high-maintenace critter? An addiction to those types of critters would be unsustainable, financially and in respect to your time. I think we let ourselves become addicted to herps, because it is rewarding and is actually pretty sustainable for the most part.
