Did you placed any water container in their cage ? I think they may need a smaller water container for drink but they never drink any water (I placed before.) . I think the only way they get water was from the mouse blood . I use repti sand as their substrate cause I don't want to place water container inside . If the substrate contacts water , the soaking sand will makes serious trouble for me . Do you have any good recommend about better substrate ? They are from desert and I think repti sand is the best substrate expects water container problem . The second is that how long time they will grow up to adult ? 2 years ? 3 years or more ? Do you have their winter cooling information ?

They are really easy to keep and eating like pigs , just some little problems confused me until now .

thanks.
