We just got a baby ball python about one and a half months ago. About four weeks ago he got some symptoms of RTI but when we spoke to the people at the pet store they told us to up the heat before we took him to the vet and so we did and all the symptoms went away. Now a few weeks later he is "yawning" again and there is the faint popping. All this seems to happen directly before he sheds. Other then the two he has never had any other symptoms and last time they disapeared it was directly after he shed. Any comments/help would be of great assistance. Thank you.
