I was going to take Charlie out of her tank to hang out for a bit this afternoon, but she was darting around enough that I figured she might be hungry. She looked a little more relaxed a little while ago, but she started whipping her tail (kind of like a vestigial rattle motion) when I touched her to pick her up. OK! No playing with the snake tonight.
She ate last Thursday night, and about a week earlier, after her usual winter without food. Maybe she needs bigger meals! Two small rats had been enough, and then one medium rat once she was able to manage those. Maybe she needs two medium rats.
So maybe I'll feed her again tomorrow or Tuesday and see how it goes.
