Today I picked up Giovanni's flower pot and he immediately balled. Picked him up by the middle of his body (no hissing) and he stayed balled. Held him on my flat hands for a few minutes while he looked at me and I looked at him. As I was going to put him back in his cage he suddenly un-balled and went rigid in kind of a u-shape.

Does this mean he is getting more comfortable, or does it mean he was uncomfortable being handled?
