If she still eats for you and seems comfortable without a hide then its fine. You have to know your snakes personality and judge based on that. My males are both pretty flighty so they still have medium RBI hides until they outgrow them. I still have a a large RBI hide in my female cinni's tub bc shes a nervous snake. She's 1400ish grams now. My normal and pastel both dont have them. They'd probably use them if i gave it to them but theyre just as happy without them lol.
