And it's so good to hear he has grown and also calmed down. Remember snakes are individuals with their own personalities and respond to obstacles in their spaces differently. Kingsnakes do have a affinity to be on the defensive side but can certainly be manageable with proper husbandry and feeding. But overall we need to remember that these are captive animals with wild instincts. They need to be respected and treated as such. Congrats on your success with Khyan.
