What does tour breeder say?
My Lady Spider does the wobble almost everytime I get in the snake room. She'd be in her hide and do her business but if I'm there out she comes and starts wobbling. When I get her out (if she is still in her hide) it would take a few seconds beford she starts wobbling around. For a 2.5kg that head swing is very hard to control so I have to be carerul. When I fed her for the first time she did not wobble at all and went for the rat the moment I dropped it. She wobbled after eating, before eating and this was only the first time I fed her so I suppose she must wobble while eating too! For her it seems to be stress as a big scaleless thing comes over her tub to look at ther must not be relaxing at all. When she is out she wants to explore so it might be a combination of stress and excitement.
Big text to say it might bot be just because he's hungry. And really, even if my snakes show signs of being hingry before their time, I dont feed them before I think its time. At two months a meal every 5 days is best to help him grow at a "normal" pace. Mine does best at 5 days while my 1yo do best on weekly meals. The bigger they get the longer they can wait.
