I recently acquired a young male BP in addition to my older female (with whom I've never had problems), and I'm a bit worried since I have limited experience with really young snakes (my girl was around 2 years old when I got her).

The little one has shed and eaten since I've gotten him, but I've noticed that he seems a bit off. He will occasionally 'bullfrog' up his throat, though I was thinking this was possibly a way for him to warn anything off, and today I noticed that a bubble will occasionally come out of his mouth. Sometimes he seems like he has problems opening his mouth, but I'm not sure if that is a typical juvenile snake thing. I tried to offer food last night, but he hasn't fed again.

I'm a little worried that the bubbles and bullfrog-ing might mean some respiratory issues. Any input?
