I have a 24-year old female. She hasn't had a full shed in about a year. Is this normal for her age? Just little bits of shed occasionally around her face and head. She is as healthy as ever - active, eating, pooping almost every day. She has access to 95 degrees F under her ceramic heater on her shelf. She spends a lot of time there and also outside in the sun. Have been giving her daily baths for the last week to see if that will stimulate shedding but nothing yet. We live in San Diego near the beach and have had a very rainy winter so I don't think overall humidity is an issue. Anyone have experience with an ig this age? Thanks!
