yeah i'm always right by them, hovering like a helicopter parent. also try to keep it to only 1 snek atta time. i also have an emergency tub (or pillowcase/bag) nearby i can throw it in in case or an emergency. one time i even had a broom just in case i had to fight off birds lol. i put 1 snek in a tree once on the lower branches and i am quick to grab it if it goes above my head.
be safe, have fun!
I'm yet to put mine in a tree, but love the tree pics!! I really don't have a tree with a low enough branch in my yard either. There's one branch I can barely reach, but it's quickly out of my reach, so I'm too nervous to go for it.
