After a crested gecko eats an insect or spider, it may lose some hair from its stomach lining around its throat and excrete some waste products through these hairs.

At first contact with humans, babies may bite in self-defense. It takes longer to establish trust at this age, and as a result, they lash out at the hand that feeds them too often or mishandles them.
