Ok, as long as it doesn't affect the snake's quality of life... Do you think that it might grow bigger as the snake gets older?
Thanks for the advice bcr229, I've already started with ivermectin so might as well finish the treatment, I will definitely have a look at permethrin next time (which I hope it never comes!). From what you mention (pet-quality vs breeder-quality), I guess that this kink is not something that the snake is born with? She might have taken a fall or something was dropped on her. Is this the case usually with these kind of kinks?
