Tip #1: Point the bitey end away from the face.
I just grab my bigger boas and sling them over my shoulder or just let them hang off my arms.
Caesar the retic doesnt care much to be carried around but sometimes doesnt mind. Those moments, i mostly just hold onto him however i can lol. If it a moment where he decided sitting on me wasnt his thing, i try and reel him in as fast as possible before he finds something to grab onto and break or flops on the floor and wanders away to find something to break lol.
As for measuring my snakes, not going to happen. They usually dont stretch out and sit there. I usually just wait until they do stretch out in their cage and then use that to guesstimate their size. Thats why i think I'm way off on Caesar. I thought he was 7-8 feet but i am thinking he might be longer from when had out wrestling match over a snagged lip lol.
