Gecko eating moss in moist hide

[MichC]

Hi, I have a leopard gecko, she is around 2/3 years old, I bought her off someone when she was about 1. The old owner used paper towel on the bottom of the tank, there were 2 hides, non of which were moist. I swapped the paper towel on the floor for some reptile carpet which is fine, she also now has 3 hides, one of them is a moist hide using moss, the past couple of weeks I have caught her eating the moss! It seems to be passing fine and she is still eating and drinking however I would like to know why she is doing this? Is there something I am doing wrong? And would it be best to change the substrate I use? And help and info will be appreciated, thank you

Some geckos just like moss I guess! Try some moist coco fiber (you can get the dehydrated blocks at the pet store and once you hydrate it you can store what you don't need in a large ziplock.
