Well I have a Russian Tortoise that is sick. Looking for some input as to what it might be. Heading to the Vet today to get her checked out. She hasn't eaten in 5 days and won't open her mouth. She has a clear liquid that is coming from her mouth and now sleeps with her head and feet out of her shell,this is not normal for her. I leave for the vet in a couple hours but hoping someone might know what this is. So I can have a little inside information. Here is a video of her enclosure, I don't see anything wrong but I'm a noob and have only had her for two years.

Her water bowl is a terra cotta bowl now and no longer that green dog bowl. https://www.youtube.com/watch?v=OuD0L-vvAwk
