Hi, I have a sulcata that is about 1 year and nine months old and 7 Inches long and 5.5 inches across her belly and weighs about 2.5 lbs. I keep her in an inclosure indoors. I live in Phoenix, Arizona and the temperatures range from 110 in the summer to 40 degrees in the winter at extremes. I am confused as too how old or how big she needs to be before she can start living outdoors either most of the time or 24/7. Can someone please specify when she is able to live outside?
