Hi,
Also search for "wobble" - both on here and youtube. :gj:
Stargazing is a tricky one as there are several possible causes ranging from symptom of disease, through neurological damage to "the snake just wanted to" :rolleyes:
The more worrying causes can be, respiratory infection, parasite infection, IBD and neurological damage.
It's one of those things where you want to start looking closely to see if there are any further symptoms that might help decide if it is something you need to worry about or not.
