While playing with and holding my ball for the past month I've heard popping sounds coming from his head. At first I thought it was his breathing or something, but now I can actually feel popping back a few inches in front of his vent when he moves. My husband thought it could be gas because he was constipated for a while. (never thought a snake would have that problem)hehehe
What do you guys think is wrong and do you think it is serious enough to take him to the vet? He doesn't seem to be bothered by it, he acts the same as he did before I noticed the noise.
Thanks for your help in advance
a pic of him taken yesterday with my cam phone during climb on me time hehehe
