She always eats 2 rabbits per feeding as that is the proper size and amount for her. I also give her time in between rabbits. Usually an hour or so (if that even does anything)
I don't think she was spooked, however; it happened immediately after a shed where she was pushing her belly against the cage HARD.
When I said antibiotics, that's not what I meant, I apologize. I mean, he just treated for the parasites it wasn't antibiotics it was whatever they normally give to treat snakes or reptiles for parasites. I just can't remember stuff I'm told very well- poor memory.. so I'm sorry for that confusion
The mucus like substance I found was indeed just something that came out when she peed. I'm not worried about it anymore. She is, as far as I am concerned, back to her normal snakey self.
I will continue to keep a close eye on her as always and when in doubt, take her to the vet.
Although I didn't see either of these replies sooner, I really do appreciate the help : )
