I took Cee Cee out to listen to her breathing tonight. I hated to do it...I didn't want to stress the poor thing out anymore than she already is...she is so skiddish right now. But I just couldn't hear her breathing enough without taking her out. It didn't sound as bad as before...still clicking a lot, and a little bit of the congestion...but I didn't hear the crackling. Hopefully the heat and humidity is helping. I did try to get her to go on the cool side, but she went right back over to the warm side again. I made her a moist hide, but she isn't going in it. I turned her heat pad off because she wouldn't go in her warm cave hide...it may have been getting a little too warm in there for her. As soon as I turned the heat mat off, she went back inside. I'll leave her 40 watt red bulb on overnight to keep it warm for her. Humidity is at 50%. I'll reassess in the morning and decide whether or not to call the vet.
