When the weather is good I regularly let her go outside to get some natural sunlight. She enjoys this time and she gets to graze/ destroy my vegetable garden. I grow the veggies mostly for her anyway.
She has gotten sunburns before when she has sneaked out on hot days. She will lie in the shade when its hot but her tail usually sticks out in the sun.
I was able to get more of the shed off her tail and it looks healthy except for the white areas with no scales. Ill try and attach a picture.
