Ok. Looking at the pics, it looks bigger. It's hard to believe that would go unnoticed with a physical inspection, but I know it can happen. Generally, in the case of spinal deformation, it does not go away.....at least that I am aware of. I am not a vet, but I'll stick with my diagnosis as I first called it. As long as you are happy with the snake and it is eating, it's not really a problem. I would however, recommend not breeding it if that was your plan. Before I go bad mouthing the breeder, I will say, we sometimes get in a hurry with things and they do get passed over. If this were my animal and I did notice it the problem, it would have been a free animal.

Again, as long as you are ok with the animal/situation, there shouldn't be a problem. If you are not happy, I would suggest trying to find the breeder for a refund or replacement.

Good luck.
