Oh! She is about to shed...because she is very dull and dusky...I gave her a bowl of water to swim in last night. Maybe that's it! I was concerned about a respiratory infection because she sounded a little wheezy...but she has done that before, and as Chantel pointed out, there is no signs of mucus around her nose and mouth or sneezing. Plus, my mother reminded me last night that I said that she did this before she shed last time...so that is probably it! Thanks you guys!
