Tip for arboreals....make removable perches. It will make your life a lot easier. Trying to coax little ones off perches onto a stick is not the best idea since they have very fragile spines and you can easily hurt them as well as kink their tail. I have had Pat almost 6 months now and i have actually 'held' him a total of maybe 3 times. And all 3 of them were his choice to climb on me as i was holding him on a perch and he decided to explore me and see what it was like sitting on an extra large perch(my arm).
Also another tip, make sure the perches are as thick as the snake at the most and no thinner than half his thickness. I personally give Pat perches that are about as thick as him. I was told giving too big of perches to babies can damage their spines as they try to wrap around the perch.
Something that works well are plastic coat hangers. Cut the long part and you have baby perches. I tried them but Pat hated them and grounded himself. He was happy with oak dowels. Just cant get oak dowels wet or they will mold after a while. But it works fine as Pat hates to be sprayed and spraying babies will water isnt the best idea as it lowers their body temp unless you are using luke warm water.
