Hi. I have a collard lizard who is Gravid, she has been with a male and her abdomin is big and she has the orange spots. She is just starting to dig around in her cage. Her orange spots are not as bright as before, is this a sign she is getting ready to lay? She is not acting lathargic and she is walking and even jumping around at times, but she is sleeping alittle more (on and off).
