My python is sick

Question
My young ball python is blowing bubbles every so often. Also his mouth (inside) looks swollen. He hasn't shed, but has looked ready for a few weeks now. He still eats and drinks water. Does it sound serious? Also, are my other pythons at risk?

Answer
Hey Jesus,

It sounds like an upper respiratory infection. You should check your temps and humidity levels. You should also bring him into the vet to get him treated. If you do not there is a good chance he will not survive. If you caught it earlier it could have been fixed with monitoring your temps and humidity levels.

Hope this helps, if you have any other questions please feel free to contact me again.
