One of my snakes is in her tub and I was sitting on the floor with a different snake when we started hearing this weird noise... it sounded similar to gagging, like she was trying to throw up. She also kept lunging with her mouth wide open as she was making these noises. However, she hasn't eaten yet, and she already pooped her last meal out. Her temps in the back of the tub are 85ºF and the front is 81ºF, she was in her hide until she got the scent of the rats. She is at the front of the tub wanting to be fed, she seems hungry, and she's acting fine... I don't know what it was or if I should even feed her at this point. Any thoughts?
