weezing

I just took my snake out and I noticed that his breathing is very weezy. Ive heard about RI but I dont think thats what he has because most people describe that is a popping noise and thats not how I would describe it. Im calling the vet tomorrow to set up an appointment but can anybody give me some advice on what he may have and what may have cause it.

Could you tell us about the husbandry? Temps, humidity, etc. A lot of times, improper husbandry leads to RI's, and sometimes not! However, wheezing is also a sign of RI and it is really good that you are taking your snake in to the vet.
