Puffing noise

[wizbit13]

About 2-3 months ago my better half heard my ball python making a strange noise. She described the noise as sounding like a dog trying to be sick. I was not here so I never heard it, but he has never done it again since. I have no idea if this has any relavance to my question but I thought I would throw it in just in case it helps.

Last week, I was sat in my room and heard him let off what I can only describe as a big puff of air. I went to have a look and he was making a funny wheezing noise, which lasted for a few minutes on and off. I have not heard him do it agin until tonight while sat here he just let off another big puff, but no wheezing this time.

My first idea is a respitory infection, but he is not showing any other signs of this. He only seems to do it now and again, and he seems to have control over when he does it if that makes any sense.

Any ideas would be much appreciated as I am starting to get a little concerned.

Kind regards

Adam
