Update after vet visit: strange behaviour
Yesterday I posted a video of my 3 years old hognose lady Lu acting very weird. About half an hour later she vomited spit and fur. I commented that she regurgitated but it was in fact vomit, since she ate last Friday and already pooped out her meal during the week. Afterwards she went to rest for a few hours and then went on a digging spree as if nothing happened.
We went in for a vet appointment today and she was deemed healthy. She most likely vomited because of stress caused by our recent move and the vet said that I shouldn't be too worried, especially because she's acting fine. She also got the green light to get her next meal on schedule.
Thank you to everyone who left helpful comments on the previous post!
