I got my Ball Python 4 days ago and have begun taking him out of the cage for 10 minutes every night after kids have gone to bed and the house settles down. He seems very comfortable and climbs around my hand and arm. The strange thing happened yesterday. He wrapped around my arm and begun "Undulating" but not going anywhere. It literally felt like he was massaging my arm/hand. He did not move an inch. His head and tail stayed in the same spot but he continued to "Massage" my hand for almost 10 minutes. I called Petco to ask and they laughed at me. So I'm hoping someone here could help....

Thank you
