My Girl made some new noises last night. Normally I am up with her most of the night because I am used to working Night Shift. Last Night I did not stay up. I was awaken by a weird noise that I can best describe a a Squeak. I jumped up thinking something was wrong, but she was just hanging upside down on the cage and seemed ok. Is this a normal noise? I haven't heard it before, does it mean something?

Mine make all sorts of noises. Crabbing, crying, barking, chirping, purring, yipping in their sleep. She could have been happy about something.

Since you were normally up at that time she was probably calling you by barking to see where you were. LOL If you click the word sounds it will take you to the page of different sound bytes so you can hear examples of the differences.
