Thank you Richard. I appreciate your insight and advice.
Olin is doing well. It's been 32 hours since he ate, and I'm hoping this means he's in the clear as far as regurgitation goes. I read a few other threads about overfeeding on the forum here, and one mentioned that after 24 hours the danger of regurgitation is mostly gone.
Here he is relaxing on the branch by the CHE. Most of him is behind the CHE itself though. He really favours being off the ground. I've read that baby boas are semi-arboreal in the wild. I find it neat that I'm observing similar behaviour in my little environment as well.
I got a cup full of mouse hoppers today, and they look a lot better than the rat fuzzies. The local shop owner suggested that when he's ready to eat more, that I feed 2x hoppers and then 3x hoppers before moving him up in prey size. Is this good advice? I've got a gram scale I'm going to be using to try and follow dakski's ~10% of body mass guideline.
A photo of Olin's parents from the breeder I got. Unfortunately, they replaced his mom with a giant yellow banana xD
Olin is the only snake of a big size I'm planning on having for a long while. I want to do my best to make sure he has the most optimal environment possible for growing and thriving. Thank you all for the assistance and advice you gave me on my first thread, and now as well. ^-^
