When my Sulcata bites his lower jaw gets stuck on his beak then slips off but when he does it makes a clicking sound and he seems annoyed.He is a hatchling so I don't know if it is a problem with trimming his beak??
Mine did that, and a lot of other people have said theirs have. I think its normal. Mine grew out of it in a matter of months. Its not his jaw getting stuck its him breathing through his mouth like a yawn. That makes a click sound for some reason.
