Similar to the picture above, I found that when I put mine on a tree branch outside, she was flicking her tongue like crazy, probably all the new scents, and I got lots of tongue pics. Maybe try going outside, when it is warmer of course (I see you are in also in from Illinois, and I know I don't even want to go outside right now
) or maybe try putting your snake somewhere it has never been in your house where there may be different smells. I also agree with taking lots of pictures
