I reread the part of the The Complete Ball Python Guide about respiratory infections today. I did notice Les come out of one hid and arch his back and yawn today. The tubs make it much easier to view the behaviors. According to the book that could be a sign. I check the mouth and didn't see excessive fluids as it indicates is a sever respiratory infections. The book did say open mess tops can cause infections and even though 1/2 of it was covered with the glass lid and the other part had some aluminum foil I think I that could be part of the cause.

According to the book it said watch to make sure it doesn't get worse and clean the cage daily, especially the water dish but usually at this stage correcting the environment and proactive can correct the problem. However if it appears to worsen take the animal to the vet.

I am also going to keep a close eye on the other two especially Charlotte (spider) who was sharing the enclosure with him. I hope he turns out ok.
