this may sound like an odd question. My columbian rainbow makes an odd squeak every now and then. I have had her 3 days and have heard it maybe 4 times. She doesn't seem bothered, no wheezing, etc...just an occasional squeak...almost sounds like squeaky gas? or kinda like the squeak of something dragged across glass (but she is lying still usually when it happens)..anyone have any ideas? I read about possible RI's but don't see any other symptoms and like i said it has only happened a couple times...also read somewhere it could be a flap of skin from her last shed stuck in her nostril that may occasionally drop down? i did notice her eyes look like she has some scales stuck to them...
