Recently, my Cham has turned downright MEAN . She will do EVERYTHING in her power to lunge, bite, hiss, and ambush when we have to get into her cage. We have to do liquid calcium and we try to hand water her to keep her used to people but I'm to the point that opening her cage is a dreadful moment of the day. Feeding her crickets is sometimes enough to cause her to attack at least until she sees food. I just don't know what to do to help the situation.
