Caesar used to do the exhale loudly when out too. He seems to have kind of quit doing it though.
The saliva on the doors and loud breathing were the things Rosey did but she also had a lump developing on her nose. I took her to the vet and it turned out she had a sinus infection. The vet guesses it was probably from pushing as she pushed a lot in her old Pro-Line cage(none of my snakes liked that cage but thats a different story lol).
I would personally just watch her and feed her a little on the heavy side so if the start of something is going on, you can maybe stem it before it gets bad by keeping her sedated with food haha.
Caesar has pretty much quit pushing but i also feed him a jumbo rat every 7-10 days which seems to be his happy place for food. Everyone else though is starting to get worked up because of summer. Rosey is tearing stuff apart as well as Vic, Dottie and even Gina is out nightly now doing the windshield wipe dance and climbing all over her shelf.
I keep my cages on an eternal summer and all my snakes still kind of slow down in the winter. Like now, their temps and everything are the same but they are all busy bodies. I think it has more to do with the outside pressures and stuff.
And like others said, get her out to burn off the energy.
Oh and to touch on the food part, she might need a bump up like you said. Everything all these people say i take with a grain of salt and a guideline. Your snake will be the only one who really can give you the right or wrong answer. When Caesar was going crazy, a lot of the people on the retic board told me i needed to feed him more. They said just because he is a super dwarf doesnt mean he wont eat. He is a retic still after all and while you can restrict the food all you want to have a small snake, some will take to it and some wont. Since then i just fed Caesar what looked good in him and kept him quiet and on the time frame that worked for him. All this within reason of course and it's been night an day with him. He is a very well mannered boy now and i can pet his head and do whatever. Just some food for thought.
Oh and not trying to slam anyones knowledge or advice. Just saying the best answers will come from the patient itself, your snake![]()
