Not entirely sure what you're asking but I have a few suggestions. First off how are your temps? What are you using to heat her hot side and how are you regulating it, i.e. thermostat, dimmer etc? How are you measuring the temps on the hot side? If it's too hot that could explain why she's never there. When you say weeeze do you mean she's peeing/urinating or do you mean Wheeze as in her breath is labored? If it's the latter it could be that your conditions such as heat and humidity are incorrect and she has developed a Respiratory Infection (RI) and you need to get her medical attention if this is the case.
