Hey all--I've got a 1-year old short tail that's recently started demonstrating some odd behavior...her neck has been 'puffing' out--it's not swelling or a growth of any kind, it's just filled with air; sort of like a bullfrog. She will periodically expel the air with a 'pfff' sound and the inflated portion will return to normal. Then, it will re-puff, then return to normal again, etc. She has also started propping her head up vertically on the walls of the terrarium which she hadn't typically done before, however she doesn't do this constantly, just periodically now. She did eat a large meal this past Sunday. She's not making any wheezing, clicking, or odd breathing noises besides the periodic puff of air (which does not occur audibly every time the neck skin deflates). There is no mucus or fluid coming from her nose or mouth, and when I curl her lip back the inside of her mouth looks normal. She has a very strong feeding response and flicks her tongue a lot (which is forked and extends fully). She did have a less-than-stellar shed on her last shed as she retained some skin on her face as well as eyecaps. I took her to the vet but they hardly gave me any information--just told me to rub vaseline on her face and put her in a shoebox with warm damp towels periodically to help the bad shed. Has anyone else ever seen this puffy bullfrog neck phenomena in their python?
