You most definitely can overfeed scorpions and tarantulas. I once had a rose hair that I bought off someone who didn’t have time for it anymore and the little girl was so “fat” that I had to put her in a low top cage to keep her from climbing for a few months until she slimmed down. She would have ruptured if she fell from a height of a foot or more.
I previously had an LG Stylo and now I have a Motorola G stylus. I love both of them. The stylus is kind of thin but it’s stored in the phone. I use the notepad pretty frequently so having a phone with a stylus is a must have for me.
