My sub adult female Leopard Gecko was standing on her hind legs hugging the side of the tank when I got home last night. I took her out and she was a little cold but acting normal. I just got home from class and there are several dried drops of a fluid ranging from pink to almost brown. I picked her up and checked her out and again she's acting fine. The strange fluid had to come from her, she's on paper towels so it was easy to spot. Should I be worried?
