Is it normal for snakes to yawn or perhaps its more stretching their jaw? mine has done this 3 times in the last hour.He's 20 weeks old and due to be fed tomorrow so maybe its just anticipation. He has had a bit of a growth spurt, he's been on fuzzies for 4 weeks and hes definetly longer. He last shed 15 days ago so i dont think its that and everything else is fine including his temps. Hopefully its normal and because he's growing. thanks in advance. Hope this is in the right place.
