Alright, not only has Hissy gone off feed, but she has taken to another strange behavior that is both annoying and concerning me. She has begun to, all of a sudden, burrow beneath her substrate. I used to use exclusively reptile carpet or rug. She was always fine with it. Never even once did she ever even try to get underneath it. All of a sudden, right around the same time she decided to stop eating, she began finding ways to get under the rug! Obviously I am concerned because I don't like the idea of nothing between her & her heat source but rubbermaid plastic. At the same time, it is annoying because i have to retrieve her from her new found hiding spot a couple of times each day. I try to anchor it all around the edges & I even switched to papertowel because it is easier to anchor down. Still, she always manages to find a way to snake (pun intended) her way under it. The crazy thing is, when i take her out & re-adjust the anchors in the tank & whatnot, I put her back in & aim her head towards one of her hides. She used to love these hides. Whenever i used to pick her up I would put her back in by aiming her head at her hides and she would cruise right into them. Now, she puts only the front quarter of her body into the hide until i walk away & then it is right back to looking for a way to get under the substrate. Her temps are perfect, her humidity is perfect, WTF is going on!!?? Can anyone give me any advice!!??
