I moved a flexible wood ladder that had bisected Willow’s cage, in order to clean it, and now Willow is stepping up onto a hand towel or a stick.
I’m going to shorten the stick so it’s less bulky, and then I’ll leave it by his cage to step him up out of the cage.
Don’t know why the ladder made the difference, and I’ve gotta put it SOMEWHERE, but not in the middle of his cage, I guess.
