So we've had her for a couple of years now and all has been fine. However, lately she's started to not bother finishing herself off whilst shedding so we've had to intervene. This is a regular occurrence now. And she's not eaten in the past 4 weeks. Tried her on meal worms, crickets and even wax worms. Her tail is getting worryingly thin. I've even gone to the extreme of buying her a brand new viv and ensuring the temperatures are correct. Any ideas or advice anyone?
