Boa breathing problem....

[Tim_Cranwill]

My friend's boa is three years old. She just went through a shed, and eats regularly. He said that it sounds like her breathing is labored when she's active, or that one of her nostrils is plugged. Is this common? What could be done about a plugged nose? Is it likely an RI?

p.s. He doesn't know any of the exact temps or humidity in the enclosure but does have a 8"x10" heat pad. I've told him to get the thermometers and etc so that he can get the enviroment under control. The boa is kept in a 36"(w)x18"(d)x30"(h) galss tank with a screen top.

Thanks.
