I caught a video of my ball eating today, the second time since I bought him. I noticed while looking through the video that at one point for a minute or so he will shake as he eats. Totally normal otherwise, finished eating and went into his hide. No shaking any other time that I've noticed. Totally normal feeding. Acts normal, drinks, poops, explores in the evening, etc etc. Cage temps are normal, 90 on one side and 80 on the other, 55% humidity. Is it something I should be worried about? Here's the video, you can see it starting about 7:45. I thought maybe it was the bent position his neck was in, as he stops after he shifts.
